| 摘 要： | 针对传统平面阵列天线圆极化轴比带宽窄的不足,将顺序旋转馈电技术与共面波导馈电相结合,对一种共面波导馈电的圆极化天线阵进行了改进,适当选择天线单元的旋转角度并对馈线进行相应的相位补偿,就可以增加圆极化天线阵的轴比带宽.仿真结果表明,改进后的阵列天线轴比带宽由传统的0.9%增加到3.7%,同时阵列天线的阻抗带宽也由传统的3.2%增加到6.9%.

| Abstract: | The technique of sequentially rotating the feed position is introduced to increase the axial-ratio bandwidth of a circular polarized antenna array fed with a coplanar waveguide.The axial-ratio bandwidth can be increased by choosing the rotating angle of the antenna properly and compensating a corresponding phase to the feed line.Calculated results show that the axial-ratio bandwidth of the improved array is increased to 3.7%,while the axial-ratio bandwidth of the conventional array is only 0.9%.Meanwhile,th... |
