| 摘 要： | 设计制作了一种新型的具有带阻特性的超宽带微带天线。天线采用50Ω共面波导馈电结构,辐射单元采用圆形金属贴片,在圆形贴片上开一个倒U形槽,实现了天线的带阻特性。测试结果表明:在频率段2.8-12.0 GHz内(除5.00-5.95 GHz外)天线驻波比小于2,且天线具有近似全向辐射的特性;而天线在频率段5.00-5.95 GHz内形成了阻带,从而有效阻隔了WLAN(5.150-5.825 GHz)频率段。该天线具有尺寸小,易于与微波电路集成等优点,可以用于超宽带系统。

| Abstract: | A novel UWB microstrip antenna with band-notched characteristics was designed and manufactured.This antenna was fed by a 50 Ω CPW and used a circular patch as the radiation element.By cutting an inverted U shaped slot in the circular patch,the band-notched characteristics of the antenna was realized.The measured results show that the antenna VSWR is below 2 between the frequency from 2.8 GHz to 12.0 GHz except the frequency from 5.00 GHz to 5.95 GHz,and has about omnidirectional radiation patterns;while the antenna has the notch band between the frequency from 5.00 GHz to 5.95 GHz,so it effectively eliminates the 5.150-5.825 GHz WLAN range.The antenna is suitable for applications in UWB systems. |
