摘　　要：设计一种新型双陷波超宽带单极子贴片天线,辐射贴片为酒杯型天线结构,采用对底部边缘开槽曲流的办法,实现了良好超宽带天线性能。同时对辐射贴片加载了U形和C形缝隙,分别在3.5 GHz和5.5 GHz处产生陷波。利用HFSS软件对所设计天线进行仿真验证,仿真结果与实测结果表明,该天线在超宽带范围内能有效抑制双陷波能力,并且在通带范围有良好辐射和稳定增益特性。其天线尺寸为33 mm×26 mm×0.74 mm,便于集成在电路系统中。A novel dual band notched Ultra Wideband （UWB） monopole patch antenna is presented. Its radiation patch is the glass antenna structure and the bottom edge is slotted with meandering way, so good performance of UWB antenna is achieved. At the same time, the radiation patch is loaded with U type and C type slot, respectively, in the 3.5 GHz and 5.5G Hz notch. The design of the antenna is simulated by using HFSS software, and the simulation and the measured results show that the antenna effectively inhibites the double notch ability in ultra wideband range, and good radiation and stable gain characteristics in the pass band range. The antenna size is 33 mm×26 mm×0. 74 ram, and it can be easily integrated in a circuit system.
