摘要

在这项工作中，提出了一种用于探地雷达的超带宽天线。提出了一种新型的边缘椭圆槽维瓦尔第对映天线(AVA)。通过调整圆锥的几何形状和调整平衡轮的形状对天线进行了优化，实现了较低的截止频率(LCF)，约为1.5 GHz。给出了反射系数、辐射方向图和增益的计算结果。利用市售模拟器对天线进行了总体设计和电磁仿真。

Optimizing Cutoff Frequency in an Antipodal Vivaldi Antenna for GPR applications through a novel balun

In this work, an ultra-bandwidth antenna (UWB) is proposed for applications in ground penetrating radar (GPR). A novel Vivaldi antipodal antenna (AVA) with elliptical slot at the edges (ESE) made with FR4 is presented. The antenna was optimized by adjusting the geometry of the tapers and modifying the shape of the balun, with these modifications a lower cutoff frequency (LCF) around 1.5 GHz is achieved. Results from reflection coefficients, radiation pattern and gain are presented. The overall design and electromagnetic simulation of the antenna are made with a a commercially avalaible simulator.
