摘要

对宽带维瓦尔第天线进行了参数化研究。采用有限元设计分析软件Ansoft HFSS v 10.1对4种模型进行仿真。研究了各模型在12 ~ 20GHz频率范围内的模拟回波损耗和实现增益。相位中心的位置，表示为距离天线底部的距离d(以厘米为单位)，相对于E和h平面中各自远场共极模式(扫描角θ为0至60°)的相位，计算约束到指定的最大可容忍相位差Δφ。

Parametric study of Vivaldi antenna

A parametric study of a wide-band Vivaldi antenna is presented. Four models were simulated using a finite element method design and analysis package Ansoft HFSS v 10.1. The simulated return loss and realized gain of each model for a frequency range of 12 to 20GHz is studied. The location of the phase centre, represented as the distance d (in cm) from the bottom of the antenna, with respect to which the phase of the respective far field copolar patterns (for a scan angle θ of 0 to 60°) in the E and H-planes, constrains to a specified maximum tolerable phase difference Δφ is calculated.
