摘要
设计了一种超宽带三陷波分形天线,该天线由花朵状的辐射贴片和带有矩形缺口的接地板构成。天线的整体尺寸为42.7 mm×33.7 mm×1.6 mm,通过采用迭代两次的分形结构,有效地增加了阻抗带宽,与传统圆形天线相比尺寸减小42.3%。通过在贴片上刻蚀U型、C型缝隙,加载J型枝节抑制了WiMAX、WLAN、卫星X波段(下行)的信号干扰。测试结果显示,天线具有稳定的增益和良好的辐射特性,工作频段覆盖2.2~11.1 GHz,且在3.1~3.9 GHz、4.9~5.9 GHz、7.1~7.8 GHz频段内产生陷波。
An ultra-wide band three-notch fractal antenna was designed.The antenna consists of a radiation patch shaped like a flower and a ground plate with a rectangular notch.The overall size of the antenna is 42.7 mm×33.7 mm×1.6 mm.By using the fractal structure with two iterations,the impedance bandwidth of the antenna is obviously improved,and the size is reduced by 42.3%compared with the traditional circular antenna.By etching U-shaped and C-shaped slots on the patch and loading J-shaped branches,the interference of WiMAX,WLAN and X-band satellite downlink frequency are suppressed.The test results show that the antenna has stable gain and good radiation characteristics.The working frequency band covers 2.2~11.1 GHz,and notches are generated in the 3.1~3.9 GHz,4.9~5.9 GHz,and 7.1~7.8 GHz frequency bands.
