1. A wireless power receiver, comprising:

  • an antenna configured to receive radio frequency (RF) power transmission waves via a plurality of slots defined by a metal plate, wherein each of the plurality of slots comprises;

    at least two continuous segments that are substantially orthogonally positioned relative to each other, where;

    a first segment of the at least two continuous segments is defined by the metal plate in a first planar dimension and configured to receive RF power transmission waves having a first polarization; and

    a second segment of the at least two continuous segments is defined by the metal plate in a second planar dimension, distinct from the first planar dimension, and configured to receive RF power transmission waves having a second polarization different from the first polarization; and

    an electronic circuit configured to convert the RF power transmission waves received by the antenna into useable power for powering an electronic device or charging a battery of the electronic device,wherein;

    the antenna is coupled with the electronic circuit, andthe metal plate is configured to;

    (i) at least partially house the electronic circuit, and (ii) operate as a heat sink for the electronic circuit.
