摘　　要：本文提出了1种宽波束左旋圆极化微带贴片天线,天线由方形微带贴片和4个大小相同的矩形金属块组成,通过在微带贴片周围添加4个大小相等矩形金属块,可有效增加带宽,扩展3dB波束宽度。由仿真结果表明:在2.42GHz频点,Phi=0°和Phi=90°切面上,3dB波束宽度可达188°以上。该天线结构简单,易加工,适合需要大角度的卫星通信、数据传输等领域。In this paper,a wide-beam left-handed circularly polarized microstrip patch antenna is proposed.The antenna consists of a square microstrip patch and four fectangular metal blocks of equal size.By adding four equal-sized rectangular metal blocks around the microstrip patch,the bandwidth can be effectively increased and the 3dB beam width can be extended.The simulation results show that at the 2.42GHz frequency points,Phi=0°and Phi=90°,the 3dB beam width on the cut plane can reach more thab 188°.The antenna structure is simple,easy to process,suitable for large-range satellite communications,data transmission and other fields.
