摘要

本文提出了一种多波段抑制的超宽带(UWB)天线。天线由支持3.1 ~ 15ghz辐射的辐射元件和接地面组成。天线由嵌入在接地面背面的微带线馈电。利用逆散射理论设计了微带线纵向宽度不均匀的微带线，使其在5 ~ 6 GHz和10.6 ~ 13 GHz具有频带抑制。实验结果表明，测量结果与理论吻合较好。天线在除WLAN 5 ~ 6ghz外的UWB范围内辐射正常，UWB范围外的辐射被成功抑制。

UWB antenna with multiple controlled rejection-bands

In this paper, an ultra-wide band (UWB) antenna with multiple band rejections is proposed. The antenna consists of a radiation element that supports radiation in a range from 3.1 to 15 GHz and a ground plane. The antenna is fed by a microstrip line embedded on the back of the ground plane. The microstrip line is designed to have nonuniform width along longitudinal direction by using the inverse scattering theory so as it has band rejections at 5 to 6 GHz and 10.6 to 13 GHz. A fabricated antenna shows that the measurement agrees with the theory very well. The antenna radiates properly in the UWB range except the WLAN range from 5 to 6 GHz and the radiation outside the UWB range is successfully suppressed.
