一种塔康天线的小型化设计

Design of a Miniaturized TACAN Antenna

针对传统塔康天线结构尺寸较大不适用于车载安装的问题,提出了一种圆柱阵塔康天线小型化设计方案。根据圆柱阵列天线的方向图合成原理,通过适当地减少天线阵元数量和重新设计相适应的馈电电路,使圆柱阵塔康天线的直径缩小35%以上。仿真结果表明,24阵元圆柱阵塔康天线性能符合设计要求,验证了天线小型化的可行性。

The traditional TACAN antenna is not suitable for being installed in the truck due to its big structure size.In view of this problem,a design scheme of TACAN antenna miniaturization is proposed.According to the radiation pattern synthesis principle of cylindrical array antenna,the diameter of the cylindrical array TACAN antenna is decreased by over 35%by reducing the number of the arrays and redesigning the feeding signal appropriately.The simulation results show that the performance of the TACAN antenna combined by 24 cylindrical arrays meets the design requirement,which demonstrates that TACAN antenna miniaturization is feasible.
