Abstract
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.
