The present disclosure relates to an apparatus and a method for performing transmission and reception of wireless power. The apparatus comprises: a transmission signal processing unit configured to generate a transmission data signal and perform a modulation and an amplification; a transmission antenna configured to convert the transmission data signal into an RF signal and transmit the RF signal; at least one reception antenna configured to receive at least one of the RF signal or an external signal received from the outside; a wireless power reception unit configured to harvest power from the RF signal received through the at least one reception antenna; and a reception signal processing unit configured to demodulate the external signal received through the at least one reception antenna. Since the RF signal, which is radiated by the apparatus itself, is received again and utilized for power charging, energy can be recycled.

A keyboard and mobile device are provided that include a plurality of keys installed in the keyboard or mobile device, and a radio frequency antenna device mounted below the plurality of keys.

An antenna is provided. The antenna includes a substrate having a first end and a second end opposite to the first end, wherein a direction from the first end to the second end is an extending direction of the antenna; a radiating portion; a feed-in conductor; and a ground portion electrically connected to the radiating portion, coupled to the feed-in conductor, disposed on the substrate from the first end along the extending direction, and including a main ground conductor; and a high frequency band bandwidth adjusting conductor extended from the main ground conductor along the extending direction.

In an antenna device including a high-band antenna element and a low-band antenna element that are connected to a common feed point and feeding electric power using one feed point, influence by unnecessary resonance of the low-band antenna element in a high band is suppressed. The antenna device includes a high-band antenna element and a low-band antenna element that are connected to a common feed point, an antenna-shortening inductor that is connected to between the low-band antenna element and the feed point, and a capacitor that is connected to the antenna-shortening inductor in parallel.

A device reader (101) for receiving data from a separate device (103) comprises a display (205) and a first antenna (105) for receiving data from the separate device. The first antenna (105) has a device reader antenna position relative to the display (205). A display processor (207) displays an image of at least part of the separate device (103) on the display (205). The image has an associated image antenna position corresponding to a position in the image of an antenna (107) in the separate device (103). The image is displayed such that the image antenna position is aligned with the device reader antenna position. The image may be determined from a non-customized image of the separate device (103) by e.g. rotation, scaling and positioning based on a display characteristic of the display (205), such as specifically a size, resolution or pixel-size. The approach may facilitate a user in aligning a device with a device reader when using short-range communication, such as e.g. NFC communication.
