摘要

本文介绍了一种新型单极圆微带贴片天线的特性，该天线具有用于超宽带系统的环形导电贴片。为了改善超宽带应用中的天线阻抗匹配，研究了在接平面插入矩形狭缝和在结构的圆形导片附近插入寄生元件对天线阻抗匹配的影响。Ansoft HFSS®软件是用于获得所考虑天线回波损耗频率行为的数值结果的仿真工具。这些结果与使用网络分析仪获得的测量结果进行了比较。

Analysis of monopole antennas for UWB systems with circular ring patch and parasitic element

This work presents a characterization of a new monopole circular microstrip patch antenna with a conducting patch in the circular ring form for use in UWB systems. The influence of inserting both a rectangular slit in the ground plane and a parasitic element close to the circular conducting patch of the structure is investigated in order to improve the antenna impedance matching, for UWB applications. Ansoft HFSS® software is the simulation tool used to obtain numerical results for the return loss frequency behavior of the considered antenna. These results are compared to the measured ones obtained using a network analyzer.
