摘要
A broadband and high-gain circularly polarized antenna based on electromagnetic band gap (EBG) structures is proposed by analyzing the influence of EBG layouts on antenna performances. Compared with the reference circularly polarized antenna, the impedance bandwidth, the axial ratio bandwidth and the broadside gain of the proposed EBG antenna are significantly improved. In addition, the method of optimizing the layout of EBG structures provides a general strategy for designing broadband and high-gain EBG antenna.
