摘要

本文提出了一种阶梯状介质杆天线，它是传统锥形杆天线的简化版。5G通信的工作频率设置为28ghz。该天线结构由三部分组成:从矩形波导到圆波导的过渡部分、喇叭激励器部分和阶梯状介电杆部分。楼梯的数量被选为3。分析表明，优化后的杆半径和杆长可实现22dbi以上的高增益。3db波束宽度约为15°。在26.5 GHz到32 GHz的频率范围内，VSWR小于2。

Rod Antenna for 28-GHz Band Operation

This paper presents a stair-shaped dielectric rod antenna, which is a simplified version of the conventional tapered rod antenna. The operation frequency is set to be 28 GHz for 5G communications. The antenna configuration is composed of three sections: a transition section from a rectangular waveguide to a circular waveguide, a horn exciter section, and a stair-shaped dielectric rod section. The number of stairs is chosen to be three. The analysis shows that the optimized rod radius and length realize a high gain of more than 22 dBi. The 3-dB beam width is approximately 15°. The VSWR is less than 2 across a frequency range of 26.5 GHz to 32 GHz.
