摘要

本文探索了一种全向天线配置，该配置由由与同轴TEM喇叭相关的成形电介质透镜馈电的反射器组成。一个简单的公式描述了通过应用费马原理来控制从电介质界面出射的光线的焦散性而获得的透镜形状。基于几何光学（GO）原理，合成技术定义了反射器形状，以控制垂直平面中的天线辐射方向图。连接圆锥曲线描述了反射器母线。该研究采用全波分析来验证设计，并探索了所提出的配置，以满足两种不同的远场规范。

Shaped Omnidirectional Reflector Fed by a Dielectric Lens Associated with a Coaxial Feed Horn

The paper explores an omnidirectional antenna configuration composed of a reflector fed by a shaped dielectric lens associated with a coaxial TEM horn. A simple formula describes the lens shape obtained by applying Fermat’s principle to control the rays’ caustic emerging from the dielectric interface. Based on geometrical optics (GO) principles, a synthesis technique defines the reflector shape to control the antenna radiation pattern in the vertical plane. Concatenated conic describes the reflector generatrix. The study employs a full-wave analysis to validate the designs and explores the proposed configuration to attend two distinct far-field specifications.
