DETAILED DESCRIPTION
[0031] In order to clarify the objectives, technical schemes and advantages of the embodiments of the present disclosure, the technical schemes in the embodiments of the present disclosure are described clearly and integrally in a way that combines the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are some embodiments of the present disclosure, rather than all embodiments. Based on the embodiments of the present disclosure, all of the other embodiments obtained by those skilled in the art without creative work are within the protection scope of the present disclosure.
[0032] Generally, the performances of the all-metal antennas of the mobile device are guaranteed at the expense of ID, namely the performances of the antennas are guaranteed by increasing the clearance area of the antennas by increasing the widths of metal gaps. Specifically, the antennas must have a function of radiating outwards, but fully-sealed metal cases are not feasible. Therefore, in order that the all-metal cases have the radiation function of the antennas, the all-metal shells are usually slotted.
[0033] It should be noted that the mobile devices are also called running devices, flow devices, handheld devices, etc. The mobile devices are computing devices, including but not limited to handheld game consoles, cell phones, mobile phones, tablet computers, etc. Users can access a variety of information via the mobile devices at any time and from anywhere.
[0034] Taking the antennas of the all-metal mobile phone as an example, the metal part of the back case of the all-metal mobile phone is the antennas. In order that electromagnetic signals can be effectively radiated into space, the back case of the all-metal mobile phone must be slotted to create radiators of the antennas. Bigger all-metal mobile phone with a same screen size affects the appearance and user's experience.
[0035] A structure diagram of an all-metal mobile phone antenna is shown in
[0036] As shown in
[0037] Obviously, the design of the all-metal antennas is strictly limited to the demands of industrial design and mechanical strength, the form is single, and the sizes required by the signal radiation at various frequency bands are difficult to achieve. The all-metal antennas are narrow in bandwidth and low in efficiency. Therefore, the all-metal antennas become one of the design difficulties of the mobile devices.
[0038] In view of the above questions, one of the core ideas of the embodiment of the present disclosure is to change the positions on the all-metal back case where the radio-frequency signals are fed by switching the feed points of the antennas aiming at different frequency bands, namely changing the electrical lengths of the antennas, so that the metal antennas can achieve the sizes required by the signal radiation at various frequency bands, thereby receiving or sending the radio-frequency signals at the different frequency bands, improving the efficiency of the antennas, increasing the bandwidths of the antennas and achieving the purpose of optimizing the performances of the antennas.

[0040] Actually, the mobile devices can change their working frequencies by tuning the antennas, so as to support different frequency bands. The network signals connected to the mobile devices determine the working frequencies of the antennas of the mobile devices. The frequency bands occupied by the network signals can be determined by monitoring the network signals connected with the mobile devices; namely, the working frequencies of the antennas of the mobile devices can be determined.
[0041] Specifically, which frequency the radio-frequency signals work at is controlled by the network and basebands. Therefore, when the network signals of the mobile devices are changed, the frequency bands occupied by the network signals of the mobile devices can be determined by monitoring, and then the working frequencies at which the mobile devices send or receive the radio-frequency signals can be determined. The mobile devices can receive or send the radio-frequency signals of the working frequencies by tuning the antennas of the mobile devices. It should be noted that different network signals occupy different frequency bands; such as the network signal GSM-850 occupies the frequency band 824-894 MHz, the network signal GSM-900 occupies the frequency band 890-960 MHz, the network signal DCS-1800 occupies the frequency band 1710-1880 MHz, PCS1900 occupies the frequency band 1850-1990 MHz, etc., which is not limited to the embodiment of the present disclosure.
[0042] Step 203: Determining target feed points to be connected with metal antennas according to the frequency bands.
[0043] When determining the frequency bands occupied by the network signals, the mobile devices can determine the feed points correspondingly connected to the frequency bands according to the preset feed points correspondingly connected to various frequency bands; the feed points correspondingly connected to the frequency bands are adopted as the target feed points, namely the target feed points to be connected with the metal antennas. Specifically, the mobile devices can configure a plurality of feed points, and the electrical lengths of the antennas corresponding to various feed points are different. The electrical lengths of the antennas can be understood as ratios of the physical sizes to the radiated electromagnetic wavelengths of the antennas. The electrical lengths of the antennas can be changed by connecting the metal antennas to different feed points, thereby achieving the sizes required by the signal radiation at various frequency bands; such as, the mobile devices can configure the feed point 1 to the frequency band 900 MHz, configure the feed point 2 to the frequency band 1800 MHz, configure the feed point 3 to the frequency band 1900 MHz, configure the feed point 4 to the frequency band 2500 MHz and so on. Those skilled in the art can configure the number of the feed points and the frequency bands corresponding to various feed points according to the frequency bands of the signals supported by the mobile devices, but this is not limited to the embodiment of the present disclosure.
[0044] According to a preferable embodiment of the present disclosure, the method further includes: determining the frequency bands corresponding to the feed points connected with various ports by testing in advance, and then establishing the correspondences between the frequency bands and the feed points. The step of determining the target feed points to be connected with the metal antennas according to the frequency bands includes: searching the feed points corresponding to the frequency bands, and adopting the feed points as the target feed points to be connected with the metal antennas. According to the embodiment of the present disclosure, as a way of testing the metal antennas, at various frequency bands, better reception and transmission results of the radio-frequency information can be obtained by determining the ports through which the switches are connected with the feed points, thereby determining the ports connected to the switch at various frequency bands, namely the feed points corresponding to various frequency bands. Therefore, a feed point may correspond to one or more frequency bands, such as the frequency band 1800 MHz and the frequency band 1900 MHz correspond to the same frequency band; the correspondences between the frequency bands and the feed points can be determined according to actual requirements and test results, but this is not limited to the embodiment of the present disclosures.
[0045] Step 205: Switching to the target feed points to be connected, configuring electrical lengths of the metal antennas according to the target feed points, so as to receive and send radio-frequency signals.
[0046] In specific implementation, electric switches of the mobile devices include a plurality of ports, and each port is connected with a feed point. The electric switches are equivalent to feed point switches, called switches for short. Which frequency band the mobile devices work at is controlled by the basebands of the mobile device, the feed point switches can be switched to the best feed points according to the testing results of the antennas obtained in advance. Specifically, in a process of debugging the antennas, in order to achieve the performance requirements, the mobile devices can be switched to different ports via the electric switches, so as to be connected with different feed points. For different frequency bands, the mobile devices can configure different connection feed points of the metal antennas, wherein the electrical lengths corresponding to various feed points are different. The mobile devices can configure the electrical lengths of the metal antennas according to the target feed points, so that the antennas of the mobile antennas can achieve the sizes required by signal (i.e. radio frequency) radiation at various frequency bands, thereby receiving or sending the radio frequency signals.
[0047] As a specific embodiment of the present disclosure, the mobile devices can configure three feed points. A feed point switching diagram according to a first embodiment of the present disclosure is shown in
[0048] According to a preferable embodiment of the present disclosure, the step of switching to the target feed points includes: [0049] sub-step 20501, determining target ports corresponding to the target feed points; [0050] sub-step 20503, switching a switch to the target ports to be connected, and then connecting the target feed points via the target ports.
[0051] According to another preferable embodiment of the present disclosure, the step of configuring the electrical lengths of the metal antennas according to the target feed points includes: adopting the electrical lengths corresponding to the target feed points as the electrical lengths of the metal antennas, and then configuring the recitation wavelengths of the metal antennas.
[0052] For different frequency bands, according to the embodiment of the present disclosure, the positions on the all-metal back case where the radio-frequency signals are fed can be changed by switching the feed points of the antennas, namely changing the electrical lengths of the antennas, so that the metal antennas can achieve the sizes required by the signal radiation at various frequency bands, thereby receiving or sending the radio-frequency signals at different frequency bands, increasing the bandwidths of the antennas while improving the efficiency of the antennas, thus achieving the purpose of optimizing the performances of the antenna.
[0053] In order that those skilled in the art can better understand the embodiment of the present disclosure, the embodiment of the present disclosure is described with the following preferable embodiments.
[0054] A step flow chart of an antenna-based processing method according to a first embodiment of the present disclosure is shown in
[0055] Step 501: Determining the frequency bands corresponding to the feed points connected with various ports by testing in advance, and establishing correspondences between the frequency bands and the feed points.
[0056] Actually, before delivered, the mobile devices can determine the radiation capacity the feed points connected with various ports of the feed point switches at the various frequency bands can be determined by testing, thereby determining the feed points with the best radiation capacity corresponding to various frequency bands. For various frequency points, the feed points with the best radiation capacity are configured as the target feed points at the frequency bands, namely establishing the correspondences (equivalent to antenna test results) between the frequency points of the feed points; thus the metal antennas can achieve the electrical lengths required by the signal radiation at various frequency bands by switching the feed points, the efficiency of the antennas is improved, and the purpose of optimizing the performances of the antennas is achieved.
[0057] Step 503: Monitoring network signals of mobile devices to determine frequency bands occupied by the network signals.
[0058] Step 505: Searching the feeding points corresponding to the frequency bands, and adopting the feed points as the target feed points to be connected with the metal antennas.
[0059] After the frequency bands occupied by the network signals are determined, the feed points corresponding to the occupied frequency bands can be determined by way of searching the correspondences between the frequency bands and the feed points, and the determined feed points can be adopted as the target feed points to be connected with the metal antennas.
[0060] Step 507: Determining target ports corresponding to the target feed points.
[0061] Step 509: Switching a switch to the target ports to be connected, and then connecting the target feed points via the target ports.
[0062] According to the embodiment of the present disclosure, various ports of the switches of the mobile devices are separately connected with the feed points of the antennas. Each port is connected with a feed point of the antennas, namely there are as many feed points of the antennas as there are ports of the switch: for example, if there are three antenna feed points, the switch has three ports; if there are four antenna feed points, the switch has four ports; if there are five antenna feed points, the switch has five ports, and so on, which is not limited to the embodiment of the present disclosure.
[0063] After the target feed points are determined, the ports of the switch to be connected with the target feed points can be determined as the target ports. The mobile devices can be connected to the target feed points by switching the switch to the target ports, namely switching the switch to the best feed points according to the antenna test results obtained in advance. Taking that the switch of the mobile device has three ports as an example, as shown in
[0064] Step 511: Adopting the electrical lengths corresponding to the target feed points as the electrical lengths of the metal antennas, and then configuring the radiation wavelengths of the metal antennas, so as to receive and send the radio-frequency signals.
[0065] According to a preferable embodiment of the present disclosure, the method further includes a step of determining the electrical lengths of the feed points: acquiring the physical lengths of the metal antennas of the mobile devices; determining the electrical lengths of the feeding points according to the radiation wavelengths of various feed points and the physical lengths of the metal antennas.
[0066] Actually, the radiation frequencies of the radio-frequency signals at the frequency bands can be determined according to the frequency bands occupied by the network signals, thereby determining the radiated electromagnetic wavelengths at the frequency bands. The radiation wavelengths corresponding to various feed points can be determined according to the correspondences between the feed points and the frequency bands as well as the radiated electromagnetic wavelengths at various frequency bands. The electrical lengths of the antennas are ratios of the physical sizes to the radiated electromagnetic wavelengths of the antennas. The electrical lengths of various feed points can be determined according to the acquired physical lengths of the metal antennas of the mobile devices, the radiation wavelengths corresponding to various feed points and the physical lengths of the metal antennas of the mobile devices.
[0067] After being connected to the target feed points, the mobile devices can receive or send the radio-frequency signals via the target feed points. Specifically, the electrical lengths corresponding to the target feed points can be adopted as the electrical lengths of the metal antennas, the radiation wavelengths of the metal antennas can be configured according to the electrical lengths and the physical lengths of the antennas, and the radio-frequency signals can be received or sent according to the radiation wavelengths (or radiation frequencies).
[0068] According to the embodiment of the present disclosure, the positions on the all-metal back case where the radio-frequency signals are fed can be identified by switching the feed points of the antennas; thus the all-metal antennas of the mobile devices can achieve the sizes required by the radiation at various frequency bands, the bandwidths of the antennas are increased, and the efficiency of the all-metal antennas is improved. According to the embodiment of the present disclosure, the purpose of optimizing the performances of the all-metal antennas of the mobile devices can be achieved by switching the feed points connected to the antennas, and realizability is high.
[0069] It should be noted that in order to simply describe the embodiment of the method, the embodiment is described as a series of action combinations, but those skilled in the art shall know that the embodiments of the present applications are not limited by the described action sequence, because some steps can be carried out according to other sequences or implemented at the same time according to the embodiments of the present disclosure.
