摘　　要：为了有效抑制现有的窄带通信系统对超宽带(Ultra-Wideband,UWB)系统的干扰,文章设计了一种新型双陷波平面超宽带天线。通过在铃形辐射单元上加载互补开口谐振环、在馈电线附件添加非对称U形半波长阻抗谐振器,使得天线在3.4~3.6GHz和5.1~5.9GHz频段内实现双陷波特性;研究了实现天线陷波的原理,并分析了天线陷波结构对陷波特性的影响。测试结果表明,该天线辐射方向图和增益特性良好,能够有效地抑制全球微波互联接入(WiMAX)和无线局域网系统(WLAN)的干扰。A novel planar ultra-wideband（UWB） antenna with double band-notched characteristics is designed to effectively minimize the interference of existing narrow-band communication system. The bell-shaped radiation patch and the feeder line are loaded with complementary split-ring resonator（CS- RR） and asymmetric U-shaped half wavelength impedance resonators, respectively, to achieve the double band-notched characteristics within the frequency range between 3.4-3. 6 GHz and 5. 1-5. 9 GHz. The mechanism of band-notch is discussed and the influence of antenna configuration is ana- lyzed. This antenna is fabricated and tested. The results show that this antenna has good radiation patterns and gain curve and is capable of restraining the interference of both the WiMax and Wireless Local Area Network（WLAN）.
