Research on a Dual-Mode Highly Isolated Conformal Thermo Stability Antenna

摘要: 为了确保飞行器在高速飞行过程中产生的高热量，不在飞行器规定的飞行时间内传递到内部的天线单元表面，造成天线温度过高，引起天线失效等问题的发生，设计了一款共形耐高温天线。该天线可同时工作在L/S/C频段，具有双模、高隔离、低剖面、小型化、与弹体共形，能耐受飞行器高速飞行过程产生高热等特点。仿真结果与试验结果表明，该天线在高温情况下达到了良好的性能指标。

Abstract: In order to ensure that the high heat generated by the aircraft during high-speed flight is not transmitted to the internal antenna unit surface within the specified flight time of the aircraft, causing high antenna temperature and antenna failure, a conformal thermo stability antenna has been designed. This antenna operates in the L/S/C frequency band simultaneously, with characteristics such as dual-mode, highly isolation, lowly profile, miniaturization, conformal to the projectile, and the ability to withstand high heat generated by high-speed flight of aircraft. Simulation experiments have shown that the antenna has achieved good performance indicators.
