摘　　要：针对卫星移动通信系统,文中设计了一种新型圆极化微带天线。通过使用四臂"L"形探针、寄生层叠结构和带状线馈电网络实现了宽带、宽波束和双圆极化工作。对原理样机进行测试,结果表明,天线在20%的工作带宽内电压驻波比<2.0∶1,轴比<3.2 d B,3 d B波束宽度>120°。A wideband and widebeam microstrip antenna for satellite communication system is presented. By feeding the stack dielectric with four orthogonal inverted-L-shaped pins, left and right hand circularly polarized operations are obtained. The proposed antenna is fabricated and Obtain 20% relative bandwidth, 3.2 dB axtial, and better than 120°3 dB-beamwidth which is suitable for satellite system.
