Abstract:
本文就制约星载有源多波束相控阵天线工程化应用的有源相控阵多波束收发隔离问题提出了增加扼流结构改善收发隔离度的方法，对多波束射频通道高密度集成技术提出了多通道芯片与化合物芯片的混合集成的方式，对星载高效热控问题提出了主辅散热面相结合、预埋槽道热管的方式，各项技术均经过了仿真验证和工程应用，相关方法可显著提升星载多波束相控阵天线的电气性能和环境适应性，实现天线系统的小型化、高集成度设计。
In this paper, we propose a method of using the choke structure to improve the transmittance isolation of active multi-beam phased array antenna, which restricts the application of satellite-borne multi-beam phased array antenna, and propose a hybrid integration method of multi-channel chip and compound chip for the high-density integration technology of multi-beam radio frequency channel. The method of combining main and auxiliary heat dissipation surfaces and preembedded heat pipe in the side panel is proposed for efficient space-borne thermal control. All the technologies have been verified by simulation and engineering applications. This method can significantly improve the electrical performance and environmental adaptability of space-borne multi-beam phased array antenna, and realize the miniaturization and high integration design of antenna system.
