摘要
文章提出了一种新型的内寄生贴片环形天线,在其周向该天线具有近似均匀辐射的方向图特征。作者依照文章技术加工测试了一个空气介质的环形天线,仿真与实测结果吻合良好,天线最大增益达到2.66dBi,其工作带宽(S11<-10dB)为1.53GHz到1.61GHz,内寄生贴片的引入使得该天线在其轴向的尺寸仅有0.11波长。
An omnidirectional tubby air patch antenna is proposed and fabricated.The antenna radiates vertical-polarization with gain varies from 2.5 to 2.66dBi over a full 360°.A parasitic parallel patch was used to achieve antenna size shrink,providing 0.11λin antenna axial direction.The measured band S11<-10dB is from 1.53GHz to 1.61GHz.
