摘　　要：本文提出了1种加载枝节的圆极化矩形环天线。首先通过合理设计矩形环的长和宽,使环形天线在1.575GHz频段谐振;然后在矩形环的转角处加载开路枝节,通过调节开路枝节的长度,并弯折小型化,使环天线可以辐射圆极化波。结果表明,该环天线的阻抗频带(JS11<-10dB)为1.47~1.64GHz,3dB轴比频带为1.54~1.64GHz,可以在1.575GHz频段谐振并辐射圆极化波。所提出矩形环天线的转角开路枝节,可以有效产生圆极化辐射,这种机制可以应用在各类需要产生圆极化波的天线中。This letter proposes a circularly polarized(CP)rectangle loop antenna with stubs.By proper design the width and length of rectangle loop antenna,the antenna can resonant at 1.575GHz bands.Two stubs are added at the corners of the rectangle loop antenna.By properly adjusting the length of two stubs,and meandering to reduce size,the antenna can radiate the circular polarization(CP)wave.The results show that the impedance bandwidth(S11<-10dB)is 1.47~1.64GHz,the 3dB axial ratio(AR)bandwidth is 1.54~1.64GHz.The antenna is capable to radiation CP wave at 1.575GHz bands.The proposed open stubs at the corner of rectangle loop antenna,can randiate CP wave effectively.This idea can be used in many antennas to radiate CP wave for various application scenarios.
