摘要

未来的移动通信系统是基于数字波束形成的多波束相控阵系统。多波束是通过电子扫描产生和扫描的。宽带圆极化天线是这种通信结构的重要组成部分。本文介绍了一种采用环形贴片天线的s波段2times2阵列天线的实现和实验评估。在2.1-2.7 GHz频率范围内实现的指向性增益为9 dBi。在1ghz的频率范围内测量输入2:1的驻波比

Broadband circularly polarized annular ring array antenna for wireless communications

Future mobile communication systems are based on digitally beam formed multibeam phased array systems. The multibeams are generated and scanned using electronic scanning. The broadband circularly polarized antennas are important element in this communication structure. This paper presents implementation and experimental evaluation of a 2times2 array antenna using annular ring patch antenna at S-band. The achieved directivity gain is 9 dBi over frequency of 2.1-2.7 GHz. The input 2:1 VSWR is measured over frequency range of 1 GHz
