单极X频段小型化天线的设计与互扰仿真

为满足船载测控设备海上标定、校验跟踪参数的需要, 一般采用放信标球的方式，同时为克服信标球在空中随气球旋转给跟踪带来的不利影响，信标天线必须采用组阵方式。由于信标球是一个小球体，安装位置受限，组阵信标天线在满足天线指标的情况下，必须满足小型化和良好互扰性要求。文中设计了一个小型化X频段天线,通过分析比较，最终采用短单极子结构,在垂直方向具有全向性。通过HFSS的仿真和参数参数优化,得到了结构参数和性能参数。通过单个天线性能仿真，以及天线组阵仿真的结果可知,所设计的天线指标上完全满足使用要求,具有天线结构紧凑、易于加工的优点;同时,本文所采用的建模、仿真方法、对其它相关天线设计也有一定的参考价值。
