文章提出一种应用于卫星通信的小型化双频天线.为了实现天线的小型化和双频段工作,在圆形单极子天线上进行了削顶和矩形切割操作;为了有效扰动电流路径而进一步缩小天线尺寸、扩大天线带宽,在天线上表面和下表面又分别刻蚀了圆环槽和对称C型槽,改善天线的阻抗匹配.天线最终尺寸为16mm×18.5mm×1.6mm.利用电磁仿真软件对天线性能进行了仿真,结果表明:该天线能够在4.76 GHz～9.25 GHz和10.46 GHz～14.2 GHz两个频段内工作,最大增益为5.9 dBi,平均增益为4 dBi,且满足圆极化条件,具备良好的辐射特性.

In this paper,a miniaturized dual-band antenna for satellite communication is proposed.In order to realize the miniaturization of the antenna and dual-band operation,the topping and rectangular cutting operations are carried out on the circular monopole antenna;In order to effectively disturb the current path and further reduce the size of the antenna and expand the antenna bandwidth,the torus groove and symmetrical C-slot are etched on the upper and lower surfaces of the antenna to improve the impedance matching of the antenna.The antenna fina...
