摘要
提出了一种新型结构的共面波导超宽带（UWB）天线．该天线由一个半圆形金属贴片和一个翼形结构的金属地板构成，这种平面印刷结构的天线不但具有超宽带性能，而且体积小、结构简单、加工简便．实测天线的-10dB反射损耗的频率覆盖范围为3．6-11．0GHz。阻抗带宽达到3倍频．这种天线很适合应用于目前的短程超宽带通信系统。
A novel ultra-wide band （UWB） shaped metal ground plate is presented. The p printed antenna with a semi-circular metal patch and a wingplanar antenna has an ultra-wide band and small size. It has a simple structure, therefore is easy to fabricate. Its measured - 10 dB retum loss bandwidth covers a frequency range between 3.6 GHz and 11.0 GHz. in other words, the ratio impedance bandwidth reaches 3 ： 1. This type of antenna is suitable for short-distance UWB communications.
