中文摘要: In this paper, a novel corrugated ground loaded with medium is proposed for enhancing the directivity of circular polarized patch antenna. Different from the suppression of surface wave propagation in the choke grooves, the proposed corrugated structure can modulate surface wave distribution and reradiate parts of surface energy into free space, resulting in the beaming effect. The radiation performance of this circular polarized patch antenna with grooves and medium loaded in the ground is investigated by using finite difference time domain method. The simulation results show that the designed antenna resonates around 10.35 GHz, where the axial ratio is less than 3 dB. Furthermore, the antenna gain reaches 13.2 dBic, which is improved by about 7 dB in comparison with circular polarized patch antenna on the flat ground. The physical mechanism for antenna performance improvement is described as well.
