Abstract:
An energy transfer system, comprising:antenna elements arranged to face a source of energy, said energy coupled thereto, each of said antenna elements having a first surface facing the source of energy, and a second surface opposite said first surface and facing away from the source of energy; a plurality of shielding layers, each shielding layer located facing said second surface, such that each of said antenna elements is coupled between said source of energy and said each shielding layer, said each shielding layer including first and second apertures arranged to receive the energy, said first and second apertures operating to separate a first part of the energy having a first polarization from a second part of the energy having a second polarization, where said first aperture is positioned to receive said first part of the energy, and said second aperture is positioned to receive said second part of the energy; a plurality of energy receiving boards, each board including first and second circuit portions spaced apart from each other, said first circuit portion including a first diode and operative to couple said first part of the energy to produce a first output signal corresponding to said first polarization, said second circuit portion including a second diode and operative to couple said second part of the energy to produce a second output signal corresponding to said second polarization, said second circuit portion using same antenna element as said first circuit portion to couple the energy; and means for appropriately coupling said first and second output signals to sum the energy received by said each board of said plurality of energy receiving boards; and a plurality of resistors, each resistor coupled between each shielding layer, said plurality of resistors arranged to appropriately reverse bias said first and second diodes when the energy is being received, and said plurality of resistors are arranged to provide a discharging path to protect said first and second diodes when the energy is removed, wherein said first and second output signals of each antenna element are connected in a series connection or a parallel connection such that said antenna elements are connected.
