The present invention relates to a method and an apparatus for controlling a wireless power receiver including a near field communication (NFC) antenna. A method for controlling a wireless power receiver including a near field communication antenna and a wireless power antenna according to one embodiment of the present invention comprises the steps of: sensing, by an NFC protection module, power generated from the near field communication antenna; blocking, by the NFC protection module, the power applied to an NFC control module when the magnitude of the power satisfies the blocking condition; and applying the blocked power to a wireless power control module, or discharging the blocked power, by the NFC protection module.

One example discloses a near-field electromagnetic induction (NFEMI) antenna, having: a core; an electric antenna including an electrically conductive surface; a magnetic antenna including a first coil coupled to a second coil; a first feeding connection coupled to one end of the first coil; a second feeding connection coupled to another end of the first coil and coupled to one end of the second coil; wherein the first and second feeding connections are configured to be coupled to an electrical apparatus; wherein another end of the second coil is coupled to the electrically conductive surface; a magnetic permeable material between a first side of the magnetic antenna and the core; and wherein the first coil, the second coil, the magnetic permeable material, and the electrically conductive surface are wrapped around the core.

An electronic device includes a housing antenna formed from a conductive material. At least parts of a side member and a rear cover that constitute the housing of the electronic device are used as an antenna. Accordingly, radiation patterns generated by this antenna are formed on the rear surface of the electronic device as well as at the upper portion of the electronic device. It is therefore possible to perform wireless communication with higher accuracy.

The at least one controllable resonating capacitor determines a resonance frequency of the antenna device. An object of the invention is to provide a compact antenna device which can obtain a desired matching characteristic without using a separate matching circuit which limits miniaturization of the antenna system as a whole and forms a factor of limiting the efficiency of the antenna and raising cost when the antenna is incorporated into the terminal.

A NFC circuit and the radiator are coupled at a first node; a non-NFC circuit and the radiator are coupled at a second node by using a non-NFC feeding path, the non-NFC feeding path includes two capacitors with different capacitances. The radiator forms a first part between the first node and the second node. The radiator includes a second part, one end of the second part is coupled to the ground, and the other end is connected to the first part. An electrical length of the second part is less than a quarter wavelength corresponding to a resonance frequency of a low frequency signal, and the electrical length of the second part is greater than an electrical length of the first part. The radiator includes a third part from the first node to an endpoint of the radiator.

A wireless power system may use a wireless power transmitting device to transmit wireless power to a wireless power receiving device. The wireless power transmitting device may have microwave antennas that extend along an axis in a staggered arrangement. In the staggered arrangement, the microwave antennas are positioned on alternating sides of the axis. Each microwave antenna is elongated along a dimension that is perpendicular to the axis. Multiple antennas may overlap a wireless power receiving antenna in the wireless power receiving device. Control circuitry may use oscillator and amplifier circuitry to provide antennas that have been overlapped by the wireless power receiving antenna with drive signals. The drive signals may be adjusted based on feedback from the wireless power receiving device to enhance power transmission efficiency. The system may have a wireless power transmitting device with inductive wireless power transmitting coils.
