A linear to circular polarizer based on frequency selective surface operating 30GHz applications

摘要

The Paper presents a FSS which theoretically converts linear polarization to pure circular polarization at the center frequency 30GHz. The polarizer consists of new structure printed on a RT-5880 substrate. In order to decrease size of traditional design of Jerusalem-cross, a ring is used in the center of FSS. The polarizer provides the required 90° phase difference between the TE and TM polarizations, which are equal in magnitude.
