摘要
设计了一种具有铲形终端微带馈电椭圆缝隙及枝节调节和接地板阶梯凹槽的超宽带（UWB）天线。利用仿真软件HFSS分析了铲形半椭圆、椭圆缝隙及枝节、半圆切槽、接地板与辐射体间隙、接地板三角形切角和阶梯凹槽等结构对天线性能的影响,对天线结构参数进行了优化。实测天线的阻抗带宽为2.8~12.0 GHz,在3.1~10.6GHz范围内基本呈全向性,并且具有较稳定的增益,约为2.5~4.6 d Bi。该天线可广泛用于无线通信领域。
A novel microstrip-fed spade terminal elliptical slot UWB patch antenna with minor dendritic adjustment and the ground stepped groove was designed. Simulating software HFSS was used to analyze and optimize the structure parameters. Results show that the impedance bandwidth of the antenna is in 2.8--12.0 GHz and the proposed antenna has nearly omni-direction characteristic over the emire operating bandwidth of 3.1-10.6 GHz and stable gain of 2.5--4.6 dBi.The proposed antenna can be widely used in wireless communication filed.
