Abstract
This paper introduces a 1-bit circularly polarized antenna designed specifically for Ku-band LEO satellite communications. The antenna exhibits a wide bandwidth, spanning from 10.7 to 14.5 GHz, and achieves a switchable radiation phase by manipulating the on-off states of PIN Diodes. With its broadband characteristics, the numerical simulation demonstrates a -10dB reflection coefficient bandwidth of 10.68 to 14.67 GHz. Moreover, the 2x2 array antenna delivers a gain exceeding 8 dBi at 11.7 GHz and 9 dBi at 14 GHz, respectively.
