Design of a Circularly Polarized 8×8 Patch Antenna Array Using a New Series-Parallel Feed
In this article, A novel 64-element high-gain circularly polarized patch antenna array in the a-band is presented. Sequential rotation technique is employed here and the patches are excited by a new series-parallel feed power distribution network with microstrip transmission lines to improve the antenna performance. The results achieved show that the microstip antenna array provides a minimum peak gain of 24.4dBi at the center frequency 29GHz. The input return loss less than -10dB bandwidth of the array is about 12.2 , and the 3dB axial ratio bandwidth is achieved as 5.9 . The proposed a-band circularly polarized antenna array has the advantages of low-cost, less weight, compact construction and easy to be integrated with F/microwave active circuits, and allows a good prospect of application in the phased array radar and satellite communication systems.
