Problems solved by technology

However, when the antenna front is set on the back of the solar panel, although the radiation area of ​​the antenna is increased, when the antenna is working, the metal substrate of the solar panel will interfere with the signal to a certain extent, thus affecting the quality of satellite communication
[0005] From the above analysis, it can be seen that the radiation capability of the existing antennas integrated with solar panels is still limited, resulting in a weak communication load capability of the earth-orbiting spacecraft. Therefore, it is necessary to redesign the antenna to improve the radiation capability, thereby Improving the communication payload capacity of low-orbit spacecraft

Description

technical field [0001] The invention belongs to the technical field of antennas, in particular to a low-cost transparent phased array antenna for low-orbit spacecraft. Background technique [0002] When the spacecraft is operating in low orbit, its communication to the ground has the advantages of short transmission delay and small path loss. For example, the current mobile satellite communication (Iridium and Global Star systems, etc.) and the space-based Internet of Things all use LEO ( low-orbit) satellites. If an inter-satellite transmission link is established between a low-orbit spacecraft and a GEO (high-orbit) satellite, the communication coverage of the low-orbit spacecraft to the earth can be improved. With the increase of ground service demands, the demand for low-orbit spacecraft communication loads will transition from the single working mode in the past to the multi-task mode. This change in business requirements requires the communication load of low-orbit s...
