ABSTRACT:
A low noise dual polarization electromagnetic power reception and conversion system is disclosed. It comprises a first plurality of conducting elements performing a bandpass function on incident waves, a second plurality of antenna units, located behind the first elements, performing a power reception and conversion function, and a third plurality of conducting elements located behind the antenna units, performing a bandstop function on incident signals. A layer of lossy material is optionally disposed behind the third elements to absorb any wave passing through them. This system can be used to achieve high efficiency power reception and conversion and also reduce levels of radiation of both harmonics of the powering frequency and intermodulation products formed by nonlinear mixing of signal wavefields from other users of the radio spectrum with the powering signal wavefield.
