摘要: 针对超宽带通信与现有的民用通信存在频带交叠的问题,提出一种使用共面波导馈电的具有双陷波特性的超宽带(UWB)天线.通过在共面波导馈电线底面引入2条接地的寄生贴片来实现频段内的双陷波特性.研究结果显示,该天线在3.1~10.6 GHz的频带范围内具有良好的阻抗特性和辐射方向特性,其中在5.15~5.35 GHz和5.75~5.85 GHz范围内具有陷波特性.

关键词: 共面波导, 陷波, 超宽带, 寄生贴片

Abstract: For solving the problem of band overlap between the ultra-wideband (UWB) communication and existing civil communication,a new type of coplanar waveguide fed UWB antenna with Dual band-notched characteristics is proposed. Two parasitic strips on earth plate was applied to realize the band-notched characteristics. The designed antenna operates on the ultra-wideband efficiently, except for the bandwidth of 5.15~5.35 GHz and 5.75~5.85 GHz for wireless local area network application. Research results show that the antenna provides perfect input impedance and pattern properties within 3.1~10.6 GHz.
