1. A bidirectional wireless power transceiver, comprising:

  • a bidirectional power converter configured to;

    convert a power input signal to an alternating current (AC) power output signal at a wireless power operating frequency when configured in transmit mode, andconvert a received power AC signal at the wireless power operating frequency to a direct current (DC) power output signal when configured in receive mode; and

    an antenna operably configured to;

    generate an electromagnetic near field in a coupling mode region at the wireless power operating frequency from the AC power output signal when configured in transmit mode, andgenerate the received power AC signal from the electromagnetic near field in the coupling mode region at the operating frequency when configured in receive mode.
