摘　　要：本文提出了1种基于十字枝节加载交叉振子的宽带高增益双极化卫星通信天线。通过在交叉又振子上加载1个十字枝节,从而使得该交叉振子天线的2个极化方向增益都显著提高。基于此十字枝节加载的交叉振子双极化天线在5.87~8.50GHz频段范围内满足VSWR<2(相对带宽为37.7%)。水平极化增益和垂直极化增益在整个工作频段内均大于5.8dBi,最高增益约10 dBi。A broadband high gain dual-polarization Satellite Communication antenna based on cross branch loaded cross dipole is proposed in this paper.By loading a cross branch on the cross dipole,the gain in both polarization directions of the cross dipole antenna is significantly improved.The cross dipole dual-polarization antenna based on cross branch loading satisfies a VSWR<2(relative bandwidth 37.7%)in the frequency band range of 5.87 to 8.50 GHz.The horizontal polarization gain and vertical polarization gain are both greater than 5.8 dBi over the entire operating frequency band,maximum gain approximately 10 dBi.
