摘要

安装在基板上的螺旋天线的单向辐射需要一个接地面的存在。在这项工作中，我们陆续说明了介电材料和地平面对平面等角螺旋天线(PESA)关键指标的影响。为此，对安装在几种具有不同介电特性和厚度的衬底上的PESA进行了建模和仿真。我们引入了在接地面的支持下在螺旋臂上流动的三次电流。

On the Influence of Ground and Substrate on the Radiation Characteristics of Planar Spiral Antennas

The unidirectional radiation of spiral antennas mounted on a substrate requires the presence of a ground plane. In this work, we successively illustrate the impact of dielectric material and ground plane on the key metrics of a planar equiangular spiral antenna (PESA). For this purpose, a PESA mounted on several substrates with different dielectric properties and thicknesses is modeled and simulated. We introduce the tertiary current flowing on spiral arms when backed by a ground plane.
