Abstract
The utility model relates to a Ka band satellite communication antenna which comprises a main reflecting surface, an auxiliary reflecting surface, a feed source, a feed system and an elevation angle adjusting device, wherein the feed system comprises a polarizer, an impedance converter, a transmitting-receiving duplexer and the like, the auxiliary reflecting surface is installed on the main reflecting surface through a bracket, the elevation angle adjusting device comprises an adjusting bracket, a connecting seat, a locking bolt and the like, and the auxiliary reflecting surface is in a ring-focus structure. When signals are emitted by the Ka band satellite communication antenna, the signals reflected to a side lobe at a far angle are small, signal bundles are concentrated and the signals have good quality. The feed source is in a flare angle variation structure, has high efficiency, is suitable for frequency bandwidth and is easily processed. The Ka band satellite communication antenna has small and compact integrated structure, the manufacturing cost is low because the projected diameter of the main reflecting surface is only 0.6 meter, and elevation angles and azimuth angles can be conveniently adjusted. By adopting a structure that the auxiliary reflecting surface is installed on the feed source, the utility model can further reduce the size of the antenna, thereby facilitating transportation and installation.
