摘要：
A broadband circularly polarized patch antenna with suspended structure is proposed. The suspended patch has an indented edge and a gap-coupled feed. By optimizing the geometries of the antenna, a wide impedance bandwidth of 1.26-1.965 GHz and an axial ratio bandwidth of 1.51-1.68 GHz are obtained. The antenna with simple structure is simulated and measured, and the results show that the bandwidth of the patch antenna is successfully broadened by using the suspended configuration, indented edge and gap-coupled feed.
