摘　　要：提出并制作了能避免来自WLAN和X波段卫星通信系统干扰,具有双陷波特性的超宽带天线。该天线印制在介电常数为4.4的FR4材料上,整个天线的尺寸为22 mm×31 mm×1.6 mm。通过在辐射贴片背面和地面之间添加由L形结构结合调谐枝节形成的新颖背面寄生单元使天线具有两个陷波。该设计使用HFSS软件仿真,仿真与测试结果表明所提出天线结构实现了双陷波功能。A ultra-wideband antenna with dual band-notched properties is designed and made to avoid the interference from wireless local area network and X-band satellite communication systems. The antenna is printed on the substrate material that is FR4 with relative permittivity of 4.4. The total size of the substrate is 19 min×26 mm× 1.6 mm. A pair of conductorbacked plane that adds a tuning stub in the L-shaped structure to make the antenna have dual band-notched characteristic. The antenna parameters have been simulated by using the HFSS. The simulated and shows that the novel solution can make the antenna have two band-notched function.
