1. A receiver unit for receiving wireless power signals to charge a power source of an electronic device, said receiver unit comprising:

  • a printed circuit board (PCB) having a first side and a second side;

    an electronic circuit mounted to the first side of the PCB, wherein the electronic circuit is positioned at a center region of the first side and includes a plurality of rectifiers;

    at least two first dipole antenna elements printed on the first side of the PCB, whereinat least one of the first dipole antenna elements is electrically coupled with one of the plurality of rectifiers, anda first of the at least two first dipole antenna elements has a first polarization that is different from a second polarization of a second of the at least two first dipole antenna elements;

    a ground plane positioned on the second side and opposite to the center region of the first side, and;

    at least two second dipole antenna elements printed on the second side of the PCB, wherein;

    each of the at least two second dipole antenna elements is electrically coupled with the ground plane, anda first of the at least two second dipole antenna elements has the first polarization and a second of the at least two second dipole antenna elements has the second polarization;

    the first of the at least two first dipole antenna elements and the first of the at least two second dipole antenna elements operatively form a first dipole antenna having the first polarization; and

    the second of the at least two first dipole antenna elements and the second of the at least two second dipole antenna elements operatively form a second dipole antenna having the second polarization, that is a different polarization from the first polarization of the first dipole antenna.
