Abstract
The invention discloses a satellite-borne wide-beam corrugated horn antenna and aims to solve the problems that an existing horn antenna cannot meet various requirements for high power, high efficiency, wide frequency band and wide beams at the same time and is not suitable for some low-orbit satellite communication. The antenna comprises a 90-degree corrugated horn antenna body, a diaphragm circular polarizer and a circular waveguide coaxial converter; one end of the 90-degree flare angle corrugated horn antenna body is connected with one end of the diaphragm circular polarizer; the other endof the diaphragm circular polarizer is connected with the circular waveguide coaxial converter; the 90-degree corrugated horn antenna body comprises a first circular waveguide section; the opening end plane of the first circular waveguide section is provided with three corrugated grooves with 90-degree flare angles; and the surface profile of the 90-degree corrugated horn antenna is circular. Thesatellite-borne wide-beam corrugated horn antenna of the invention has the advantages of wide wave beam, wide working frequency band and right-handed circular polarization, can be well applied to engineering applications such as satellite communication and the like, and the wave beam forming of the satellite-borne wide-beam corrugated horn antenna meets the requirements of earth matching.
Description
technical field [0001] The invention relates to the technical field of satellite communication, in particular to a satellite-borne wide-beam corrugated horn antenna and its application. Background technique [0002] In recent years, in satellite communication, in order to effectively cover a specific area, reduce the interference of adjacent cells and improve efficiency, the radiation pattern of the spaceborne antenna is required to match the shape of the service area, and more and more attention has been paid to the shaped antenna. , The horn antenna has the advantages of shaping, low cost, small size, low cross-polarization level, low sidelobe and good standing wave in the working frequency band, and is suitable for satellite communications with demanding antenna requirements. [0003] Among them, the three-dimensional electromagnetic beam emitted by the corrugated horn antenna to free space has the characteristics of axial symmetry, small side lobe capacitance, and low cr...
