The discrete design requires larger space resources, weight resources, thermal control resources and power supply resources, increases the design complexity, development period and development cost of the commercial satellite, and is unfavorable for miniaturization, integration, cost reduction and efficiency improvement of the commercial satellite. Satellite service software and load software are increasingly complex in function, in order to improve reliability, on-orbit programming requirements are provided, remote control uplink margin is larger, the requirement of high-speed on-orbit programming data can be met, and therefore ground measurement and control resources can be effectively utilized. Many loads operate with satellites required to adjust attitude to a particular ground target.

But the antenna gain is low, high requirements are put on the transmitting power, the development cost is increased, and meanwhile, the improvement of the data transmission rate is limited. Or a high-gain antenna with a rotating mechanism is adopted, but the rotating mechanism and the rotating feeder line have high development cost, and the rotating mechanism has heavy weight and large volume.

The phased array antenna is provided with a TR component, and the requirement on the output power of the radio frequency unit is greatly reduced. The antenna output gain is high, and a higher communication rate can be realized. The phased array antenna changes the direction of the pattern by the feed phase of the radiating element, has no rotating mechanism, and is lightweight. The phased array can realize two-dimensional beam scanning, realize simultaneous work of load and data transmission downlink in the data transmission arc section, and realize simultaneous recording, playing and real-time playback of load data, thereby effectively utilizing load resources and ground data transmission resources.
