| 摘 要： | 本文提出一种新型馈电结构的印刷角锥四臂螺旋天线。通过采用柱面共形结构馈电网络,与传统四臂螺旋天线相比极大地减小了地板安装面积及改善了阻抗带宽和轴比带宽。S11小于-10dB的阻抗带宽可达39.7%,3dB轴比带宽约22%。测试与仿真结果吻合良好。

| Abstract: | A novel broadband cone printed quadrifilar helical antenna with a new type feeding network is presented in this paper.The installed place is much reduced by using conformal feeding network and the impedance bandwidth and axial-ratio bandwidth are great improved compared with conventional quadrifilar helical antenna.The antenna can achieve an impedance bandwidth of 39.7 % for S11<-10 dB and a 3 dB axial-ratio bandwidth of about 22 %.The simulated results and measured results are presented and they are in goo... |
