摘　　要：为了满足现代通信的需求,设计了一种新型的超宽带平面天线,实现了良好的超宽频带阻抗匹配。该天线的辐射贴片与接地板结构相似,通过在辐射贴片上加载U型槽以及在馈线一侧加载新型陷波结构分别在中心频率3.5 GHz和5.5 GHz处产生陷波。天线实测与仿真结果基本相近,通带内辐射效果良好,且该天线对WIMAX及WLAN波段有很好的抑制功能,可用于超宽带系统。A new type of a ultra-wideband planar antenna achieving good impedance match was proposed to meet the requirement of the modern communication technology. The shapes of radiation element and ground plane are exactly the same. Meanwhile, a U-shaped slot is embeded into the radiating patch to obtain the notched band of 3.5GHz and a new type of band-notched structure is embeded beside the feed line to obtain the notched band of 5.5GHz. The simulated and measured results show that the antenna has a good radiating characteristic, measured results confirm that the proposed antenna is good out of WIMAX and WLAN bands and suitable for UWB system applications.
