摘要
为了降低5.725-5.850 GHz的窄带ISM(Industrial Scientific Medical)频带信号对超宽带(Ultra Wideband)信号传输的影响,设计了一种新型的小型平面印刷超宽带天线,该天线由50Ω同轴线馈电,在3.1-10.6 GHz的频带内具有良好的谐振效果和方向性.对该天线进行陷波处理,设计了一个近似U型的陷波槽,对陷波槽陷波原理进行了分析,并且对陷波槽的尺寸进行了优化,实现了在5.8 GHz的ISM频段的阻带特性.仿真和测试结果均表明,带宽覆盖了3.1-10.6 GHz,测试表明实际的带阻频段为5.6-6.2 GHz,覆盖了频率为5.725-5.850 GHz的ISM频段.此天线可适用于5.8 GHz信号干扰的超宽带应用环境.
In order to reduce the influence of narrowband ISM(Industrial Scientific Medical)signals on the transmission of ultra-wideband signals,A novel compact planar-printed UWB(Ultra Wideband)antenna feed by a 50Ωcoaxial cable was designed.The antenna has a very good resonance effect and directivity in the range of 3.1-10.6 GHz.A band-notched process was adopted.The optimized U-shaped slot was employed,and the principle of how the notch groove works was analyzed.Then the band-notched characteristic was achieved in the 5.8 GHz ISM frequency band.Simulation and test results show that the bandwidth of the antenna covers 3.1-10.6 GHz.The test result shows that the actual rejection band is 5.6-6.2 GHz,which covers ISM frequency band of 5.725-5.850 GHz.
