摘要

本文介绍了一种为穿墙探测系统设计的高增益超宽带（UWB）椭圆和圆形槽反脚维瓦尔第天线（ECS-AVA）。天线喇叭口装有椭圆形和圆形槽，以提高增益并拓宽带宽。为验证所设计天线的功效，制作了 ECS-AVA 原型并进行了测量。实验结果表明，所设计的天线能在 3.1 GHz 至 10.6 GHz 范围内有效处理信号，其阻抗带宽为 │S11│≤ -10dB。测量结果与 CST 仿真结果一致。拟议的天线在 UWB 波段的辐射模式有所改善，峰值增益从 4.8 dB 到 11.9 dB 不等。

High-gain UWB elliptical and circular slotted antipodal Vivaldi antenna for through wall detection

The paper describes a high-gain ultra-wideband (UWB) elliptical and circular slotted antipodal Vivaldi antenna (ECS-AVA) that is designed for through-wall detection systems. The antenna flares are loaded with elliptical and circular slots to improve the gain and broaden the bandwidth. To validate the efficacy of the designed antenna, a prototype of ECS-AVA is fabricated and subjected to measurements. The experimental findings suggest that the designed antenna can handle signals effectively across a range from 3.1 GHz to 10.6 GHz, as shown by its measured impedance bandwidth, with │S11│≤ -10 dB. The obtained measurements results are consistent with the results of the CST simulation. The proposed antenna exhibits improved radiation patterns in the UWB band with peak gain values ranging from 4.8 dB to 11.9 dB.
