摘要

本文介绍了一种宽带圆极化微带贴片天线的设计与仿真。天线由一个圆形贴片、一个空气层和四个探头组成。在0.25GHz频段，贴片与地面的距离仅为自由空间波长的0.058倍，实现了低姿态特性。HFSS仿真结果表明，在42.2%的带宽下，驻波比优于2，轴向比小于1.5dB，天线峰值增益为10.6dBi。

A Low Profile Broadband Circularly Polarized Microstrip Antenna

This paper introduces the design and simulation of a broadband circularly polarized microstrip patch antenna. The antenna consists of a circular patch, an air layer and four Lprobes. The distance between the patch and ground is only 0.058 times of the free space wavelength at 0.25GHz, achieving low profile characteristic. The HFSS simulation results show that VSWR is better than 2 in 42.2% bandwidth, the axial ratio is less than 1.5dB, and the antenna peak gain is 10.6dBi.
