Description

technical field

[0001] The invention relates to a manufacturing technology of a mirror scanning array antenna in the field of mobile satellite communication and mobile measurement and control, and is especially suitable for the manufacture of various satellite communication or single receiving antennas working in vehicle-mounted or ship-borne mobile satellite communication, measurement and control applications . Background technique

[0002] At present, three methods are mainly used to enable the satellite communication antenna to communicate with the satellite in the case of vehicle and ship:

[0003] One is to use a traditional parabolic antenna or an array antenna, and the azimuth and pitch are mechanically controlled to drive the entire antenna to rotate. Its shortcoming is that the structure is complex and requires a large rotation space and servo power.

[0004] The second is to use a low-profile array antenna. The azimuth plane adopts a mechanical control method to ...
