Abstract

In this paper, a novel method to enhance axial ratio bandwidth of circularly polarized (CP) patch antenna using artificial magnetic conductor (AMC) structures with LTCC technology at Ka-band is proposed. In order to improve the axial ratio bandwidth, the traditional PEC plane is replaced by an AMC plane. The AMC is composed of periodic square unit cells with truncated opposite corners. The AMC structure and the antenna are simulated using a full-wave solver and the results show a 10 dB return loss bandwidth of 30% and a 3 dB axial ratio bandwidth of 12.7%, and gain is around 7.5 dB within this band, which compared with the traditional corner-cut square circular polarization patch antenna, the axial ratio bandwidth of proposed antenna increased by 9.5%.
