摘要

本文提出了一种指数型扩口维瓦尔第型天线，在两种不同的修改下实现了高带宽和高增益。考虑到相控阵系统的集成可行性，对所提出的天线进行了设计和优化。通过优化介电常数εr = 2.5的CuClad衬底上的标准指数喇叭型Vivaldi天线拓扑结构，得到了带宽为5.12-16.34 GHz的天线。包括一个半圆作为帽槽和插槽提高天线的指向性。对缺口单元进行了参数化研究。参数化研究的结果表明，由于S参数的对称性，这些缺口元素在不改变S参数的情况下影响了辐射特性的指向性。

A Gain Enhancement Study on a Vivaldi Antenna for Radar Applications

This paper presents an exponential flared Vivaldi type antenna in two different modifications that achieved high bandwidth and gain. The proposed antenna has been designed and optimized, considering the integration feasibility of the phased array system. The proposed antenna has been obtained with the bandwidth 5.12-16.34 GHz by optimizing a standard exponential flared Vivaldi antenna topology on CuClad substrate with dielectric constant εr = 2.5. Including a half-circle as a hat notch and slots improve the antenna's directivity. The parametric study on notch elements is provided. The outcome of the parametric investigation is that those notch elements affect the directivity of the radiation characteristic without changing the S parameters due to its symmetrical characteristics.
