摘要
通过用表面电流法计算和实验发现:文中的2种圆锥形反射面天线可分别产生有效口径的半功率宽度较宽的、增益不低的扇形波束和针状波束;同时,较大的制造公差对2种圆锥形反射面天线的特性的影响不大。2种圆锥形反射面天线适合用作雷达诱饵辐射器,具有其他产生相同形状波束的天线所不具备的易于加工、成本极低的优点。
Through calculation and experiments, it is found that this new antenna has a fan beam or a pencil beam and has a high peak gain and aperture efficiency . The reflector of the new antenna is conical. This conical reflector antenna can be produced easily and has much lower cost than other types of reflector antenna of the same performance. Thus this new antenna can be used as a tow-cost radiator for radar decoy which will be destroyed by missiles.
