摘要

本文提出了一种基于人工磁导体(AMC)地平面的低姿态双臂阿基米德螺旋天线。所研究的天线产生右旋圆极化。AMC地平面由4×4方形补丁组成，没有过孔。天线与AMC地平面顶部之间的距离减小到0.02λ0。工作频率为4.5GHz。地平面平面尺寸为0.837λ0 × 0.837λ0。

A sual-arm Archimedean spiral antenna over a low-profile artificial magnetic conductor ground plane

this paper presents a low-profile dual-arm Archimedean spiral antenna over an artificial magnetic conductor (AMC) ground plane. The antenna under study produces right handed circular polarization. The AMC ground plane consist of 4×4 square patches with no vias. The distance between the antenna and the top of the AMC ground plane is reduced to 0.02λ0. The operating frequency is 4.5GHz. The planar size of the ground plane is 0.837λ0 × 0.837λ0.
