초록

In this paper, we present a new design method for a square iris polarizer to be used in dual-band (Ka-band; 20.8 ~21.2 ㎓, 30.6~31 ㎓) antenna feeds. Principles of operation of a square iris polarizer, its design concepts and methods are proposed. Based on proposed methods, a Ka- band polarizer with -35 dB return loss and 0.3 dB axial ratio is designed using the commercial software HFSS.
