    摘要： Systems and methods for polarization converters 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 polarization converter positioned between the first and second transceiver modules and configured to convert the one or more linearly polarized communication links to circularly polarized communication links. The polarization converter includes first and second frequency selective surfaces (FSSs) formed from respective first and second metalized layers of a printed circuit board (PCB), each FSS includes an array of capacitive patches and inductive traces forming an array of unit cells, and each unit cell of the second FSS is aligned with each unit cell of the first FSS.

    摘要： 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.
