摘要
设计了一种适合于径向线缝隙天线(RLSA)馈电的双圆极化馈电结构。在所设计馈电结构的基础上,仿真设计了双圆极化径向线缝隙天线。天线在11.75～12.25GHz频段内驻波小于2.0。12GHz处天线左旋圆极化增益为25.6dB,右旋圆极化增益为24.3dB,口径效率约为49%。
A kind of dual circularly polarized feed structure suited to radial line slot antenna is designed in this paper. On the basis of feed structure, dual circularly polarized radial line slot antenna has been designed. The VSWP, of the antenna is smaller than 2.0 in the frequency band 11.75-12.25GHz. The antenna gain of left hand circular polarization is 25.6dB, and that of right hand circular polarization is 24.3dB in 12 GHz. The an-tenna efficiency is about 49%.
