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.
