摘要

本文介绍了一种用于超宽带(UWB)应用的平面单极天线。为了在WLAN频段和ITU频段获得良好的阻带特性，在馈线附近设计了矩形贴片和带两个谐振器的CSRR插槽。利用CST仿真软件对该天线的性能进行了测试，结果表明该天线在3.4 ~ 13.60 GHz的工作带宽范围内阻抗匹配良好，满足了超宽带应用的要求。通过在贴片中插入一个槽并在馈线附近放置两个谐振器，可以实现双带缺口曲线。该天线具有良好的回波损耗图，具有两个陷波，首先覆盖WLAN频段，其次在7.6GHz处陷波5.5GHz。信中还显示了各频率下的表面电流分布，在Eplane和H-plane上很少有辐射方向图

A Rectangular Monopole UWB Patch Antenna with CSRR slots having dual band notch Characteristics

A planar monopole antenna for ultra-wide band (UWB) application has been presented in this letter. In order to gain an excellent band-rejection characteristic at WLAN band and ITU band, a rectangular shaped patch and a CSRR slot with two resonators near the feed line has been designed. The performance of the proposed antenna is investigated by using the software CST MW Simulator and the results achieve good impedance matching over an operating bandwidth of 3.4 – 13.60 GHz, which meets the requirement of UWB application well. Dual band notch curves have been achieved by inserting a slot in the patch and by location two resonators near the feed lines. The proposed antenna has good return loss graph having two notches first covering the WLAN band and notching the 5.5GHz second at 7.6GHz. Surface current distribution at various frequencies is also shown in the letter with few radiation pattern graphs in Eplane and H-plane
