Abstract

High gain circularly polarized substrate integrated waveguide (SIW) slotted cavity antenna is proposed using TE440 high order modes. A linear to circular polarization convertor is used in order to achieve a circular polarization (CP). The antenna has many attractive advantages such as low profile, light weight, and compact in size. Moreover, it offers both left and right hand circular polarization. High gain of 16 dBi is achieved and the efficiency is about 98%. In addition, the antenna has a good radiation pattern. Therefore, this antenna consider more appropriate for Future fifth generation (5G) wireless systems.

圆极化高增益低轮廓开槽SIW腔天线
提出了一种采用TE440高阶模式的高增益圆极化基板集成波导(SIW)开槽腔天线。为了实现圆偏振(CP),使用了线性到圆偏振变换器。该天线具有外形小、重量轻、体积小等优点。此外,它提供了左圆偏振和右圆偏振。实现了16 dBi的高增益,效率达98%左右。此外,该天线具有良好的辐射方向图。因此,这种天线被认为更适合未来的第五代(5G)无线系统。
