摘要：

A high-gain low-profile circularly polarized substrate integrated waveguide cavity antenna is proposed using TE440 high-order mode. This antenna is simply excited by a coaxial probe. A linear-to-circular convertor is used in order to achieve circular polarization (CP). The low-profile, lightweight antenna offers both left-and right-hand CP. The implemented antenna exhibits a measured gain of almost 16 dBi and simulated radiation efficiency of about 96% with good measured return loss. Measured axial ratio is almost less than 1.6 dB. Furthermore, the antenna shows a good performance radiation pattern. Measured and simulated results show a good agreement. This antenna is considered as an appropriate candidate for use in future fifth-generation wireless systems.
