Research on Key Technologies of Satellite-Borne Muti-Beam Phased Array Antenna

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 pre-embedded heat pipe in the side panel is proposed for efficient space-borne thermal control. All the technologies
