一种单脉冲形式的平板天线设计

Design of a Monopulse Flat Plate Antenna

平板天线是一种可快速展开使用及收藏的卫星通信地球站天线。因此,设计了一种单脉冲形式的L频段平板天线,采用微带平板阵列方式比常规抛物面天线更适用于车载平台的使用,避免了传统馈源形式的遮挡影响,因此,具有增益高、质量轻和尺寸小的特点。设计完成后,使用HFSS对整个天线方向图进行仿真计算,并进行优化处理。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。

The flat plate antenna is a kind of satellite communication earth station antenna that can be quickly deployed and collected.A monopulse L-band flat plate antenna is designed.The microstrip flat panel array is more suitable for the vehicle platform than the conventional parabolic antennas,thereby avoiding the shadowing effects of traditional feed forms,and has the characteristics of high gain,light weight and small size.After the design is completed,the whole antenna pattern is simulated and optimized by using HFSS.Measurement results indicate that the designed antenna has excellent electrical performance and good practicability.
