Abstract
Systems and methods for dual channel polarization filter structures are disclosed. An example wireless communication system includes a first transceiver module of a wireless communication system configured to form one or more linearly polarized communication links with a second transceiver module of the wireless communication system, and a dual channel polarization filter structure positioned between the first and second transceiver modules and configured to filter the one or more linearly polarized communication links to produce corresponding one or more filtered linearly polarized communication links. The dual channel polarization filter structure includes first and second filter channels each formed from three structural layers including at least one metalized layer printed circuit board (PCB) disposed between the remaining two structural layers, and each filter channel includes an array of filter elements each comprising at least one metamaterial absorber arrangement.
