摘要
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, the impedance bandwidth of the improved array is increased to 6.9%, compared with the conventional array whose impedance bandwidth is only 3.2%.
