| 摘 要： | 为了避免现存的窄带信号对超宽带系统的干扰,提出一种具有附加寄生单元结构的超宽带陷波天线模型.通过对天线矩形辐射贴片和接地板形状的改进,使之在超宽带的辐射频段内具有较宽的阻抗匹配特性,同时在天线背面加入两个T形寄生单元使其具有陷波特性.利用HFSS软件仿真测试天线性能,结果表明所设计的陷波天线实现对WLAN窄带干扰信号的抑制,同时在工作频段内表现出较好的全向辐射特性.

| Abstract: | In order to avoid narrow-band signal in UWB system, the band-notched UWB antenna with parasitic elements structure is proposed which size is 22 mm× 12 mm×1.6 mm. It has wider impedance matching characteristic because of the shape improvement of rectangle radiation patch and ground plane. Two T-shaped parasitic elements make the UWB antenna to have band-notched performance. Based on HFSS software the antenna simulation results show the designed antenna realizes inhibition of narrowband signals from WLAN system and has good omnidirectional radiation characteristics in working frequencies. |
