Outline
Based on the requirements of space-based telemetry transmission of launch vehicle and the strict limitations of weight, space, and energy consumption on the vehicle platform, this paper designs a miniaturized, lightweight, highly integrated and low-power consumption S-band tile type active phased-array antenna system. The system includes antenna array module, T-module array module, power divider network module. beam controller and power unit module. The article elaborates on the working principle and integrated architecture of the system, and designs several key circuits such as antenna array, T-module, highly reliable power supply unit and beam controller, etc, according to the requirements. The developed antenna system prototype has been tested in a darkroom, and its major indexes such as beam width, axial ratio, ERIP within the beam scanning range of ±60°in the azimuth and elevation plane all meet the design requirements. Compared with brick phased array antenna systems with similar functions in the same frequency band currently on the market, its volume is reduced by 45%, weight is reduced by 25%, and the energy consumption is reduced by 15%, which is more in line with the phased array antenna from the arrow-carrying size, weight, and economic application demand. It also provides guidance for the development of phased array antenna in related fields.
