This Ku-band LEO shared-aperture phased array antenna is independently developed based on an advanced phased array platform. It integrates antenna radome, thin-film elements, RF PCB, and air-supported structure into a compact flat-panel design.<\/p>

The system uses FPGA-based real-time computation to control amplitude and phase for each antenna element, enabling fast beam steering and stable satellite tracking for mobile communication scenarios.<\/p>

With a shared transmit\/receive aperture architecture, the design significantly reduces system size while improving integration efficiency, making it suitable for lightweight mobile SATCOM terminals.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
