Abstract: A mobile communication device having a wireless power receiver and wireless communications unit, in which inductors of the communications unit and the power receiver are in close proximity to each other, is provided. The mobile communication device includes a wireless communications unit including a first inductor configured to transmit and receive data via inductive coupling, and a wireless power receiver. The wireless power receiver includes a second inductor which is disposed above the first inductor and receives power via inductive coupling, a ferrite shield disposed between the first inductor and the second inductor, and a compensator disposed between the first inductor and the ferrite shield. Compensator is adapted to compensate for variations in the inductance of the first inductor caused by the ferrite shield.

Abstract: An ultra-wideband (UWB) antenna for wireless communication in proximity to a human body and between devices having no line-of-sight, includes symmetrical radiators disposed on a side of a dielectric layer, and a differential microstrip feeding line disposed on the side and an opposite side of the dielectric layer.

Abstract: A transmitting/receiving system including a transmitter/receiver and a retransmitter. The transmitter/receiver includes an antenna, a multiplexer, a mixer, a receiver, a transmitter, an IF processor, a DSP and a control module. The retransmitter includes an antenna, a transceiver and a controller. The receiver receives a main input radio-frequency signal. The transmitter transmits a main output radio-frequency signal. The transceiver receives the main input radio-frequency signal, transforms the main input radio-frequency signal into an intermediate radio-frequency signal, and transmits the intermediate radio-frequency signal. The IF processor receives the intermediate radio-frequency signal and processes the intermediate radio-frequency signal. The DSP processes the main input radio-frequency signal with the processed intermediate radio-frequency signal.
