摘　　要：介绍了超宽带天线的特点和基本理论，讨论了超宽带天线的设计方法，设计出一种新型且结构更为简单的超宽带印刷单极子天线。实验结果显示：通过在接地板上开具合适的矩形槽可以增加天线的带宽。本文设计的超宽带天线具有3．13～15．7GHz的带宽，覆盖了整个无线通信频段，并且具有良好的远场辐射特性。The characteristics of ultra-wideband technology and the basic theory have been introduced, and the design methods of ultra-wideband antenna have been discussed. An uhra-wideband printed monopole antenna with simple structure has also been designed in this paper. Experimental results show that proper slot on the ground can add the antenna＇s bandwidth. This antenna has a bandwidth of 3.13-15.7 GHz which covered the entire UWB frequency band and also with good far-field radiation characteristic.
