[Abstract]
A new low-profile design method is proposed for space-borne SAR ( synthetic aperture radar) antenna with the light-weight carbon-fiber function and packaging materials. The functional integration technology for the highly integrated system-level is studied. Furthermore, a new antenna radiating elements integrated electricity, machine and heat functions is designed. The new type of aluminum matrix composite material is used to encapsulate the packaging and power supply modules, and the antenna frame integrated with thermal control function is achieved. The results are practical significant for the development of the large high resolution and power antenna system design.
