1. A receiver device for receiving wirelessly delivered power, the receiver device comprising:

  • a housing that defines (i) a first gap within a first half of the housing and (ii) a second gap within a second half of the housing, wherein;

    the housing includes a radio-frequency-reflective material; and

    the first and second gaps are filled with a radio-frequency-transparent material;

    two wireless-power-receiving antennas housed in the housing, each of the two wireless-power-receiving antennas being configured to receive radio frequency (RF) wireless charging signals transmitted by a near-field transmitter that enter the housing via the first and second gaps, wherein;

    a first of the two wireless-power-receiving antennas is positioned adjacent to and substantially within the first gap; and

    a second of the two wireless-power-receiving antennas is positioned adjacent to and substantially within the second gap; and

    power conversion circuitry housed in the housing and electrically coupled with the two wireless-power-receiving antennas, the power conversion circuitry being configured to rectify the received RF wireless charging signals to produce a rectified electrical signal,wherein the receiver device uses energy from the rectified electrical signal to charge a battery of the receiver device or provide power to the receiver device.
