一种格里高利型卫星通信天线的设计

Design of a Gregorian Antenna for Satellite Communication

小型卫星通信车载天线要求具有高效率、低副瓣和小型化的特点。采用格里高利型双偏置天线形式对于单偏置天线更有优势,更容易实现紧凑的结构,满足小型卫星通信车载站的要求。在天线设计时进行了赋形设计,并使用商用仿真软件进行了仿真计算,利用该方法设计了一种双偏置卫星通信天线。经实测结果表明,设计的天线电气性能优良,具有良好的实用性。

Small satellite communication vehicle antenna should have the characteristics of high efficiency,low sidelobe and miniaturization.The form of Gregory double offset antenna is more advantageous for single offset antenna,and it is easier to achieve compact structure,which can meet the requirements of small satellite communication vehicle station.At the time of antenna design,the shaping design is carried out,and the simulation calculation is carried out by using commercial software.A double offset satellite communication antenna is designed by using this method.The experimental results show that the designed antenna has excellent electrical performance and good practicability.
