The antenna includes a main projector, an auxiliary projector arranged correspondingly with the main projector; The opening of the corrugated horn fed source is heading towards the projector surface of the auxiliary projector, and the corrugated horn fed source is connected with the transceiver duplex feeder; The transceiver duplex feeder and the amplifier with low noise is arranged at the back of the main projector of the antenna, and the amplifier with low noise is connected with the transceiver duplex feeder and connected with the satellite communication terminal part. The utility model takes effect that: 1. solving the problem with ultra-thin aperture of the movable satellite communication. 2. reducing the shield of the feeding part towards the antenna projector; 3. solving the interference problem, ensuring the communication quality with high gain of the receiving signal, low sidelobe and high cross, polarization and isolation degree; 4. low producing and using costs.
Description
Technical field
The utility model relates to communication field, especially a kind of mobile satellite communications device that is applicable to the extra small bore of mobile vehicles such as car, ship.
Background technology
The mobile satellite communications matching requirements that is used for mobile vehicles such as car, ship is tracking satellite automatically, and Zhuan Zhi overall dimension also is restricted simultaneously.The development of modern satellite communication terminal technology also makes and adopts the satellite communication of extra small aperture antenna to become possibility.
Another part of the applicant patent application " Ku waveband mobile satellite communication device " (application number: 02217440.0, open day: on March 19th, 2003) disclose a kind of mobile satellite communications device, its antenna-feedback system adopts feed forward type, it is the front that the feed part all places antenna principal reflection body, for extra small aperture antenna, transmission duplex feeder line, low noise amplifier in the preposition feed part formed seriously the blocking of antenna reflective face, and be all influential to gain, secondary lobe and the cross polarization isolation of receiving and transmitting signal.
Summary of the invention
The utility model mainly provides a kind of feed part of reducing to the blocking of antenna reflective face, and guarantees communication quality, lower-cost mobile satellite communications device.
The utility model solves the technical scheme that its technical problem adopts double antenna reflecting surface, feed postposition.This mobile satellite communication device, mainly comprise antenna feeder part, servo segment, monitor portion and satellite communication terminal part, antenna feeder partly comprises antenna, corrugated horn feed, transmission duplex feeder line and low noise amplifier, servo segment comprises crossbeam, pillar and base, described antenna comprises a principal reflection body, the secondary reflector with principal reflection body positioned opposite; The opening of corrugated horn feed is towards the reflecting surface of secondary reflector, and the corrugated horn feed links to each other with the transmission duplex feeder line; Transmission duplex feeder line and low noise amplifier are arranged at the back side of the principal reflection body of antenna, and low noise amplifier links to each other with the transmission duplex feeder line, and link to each other with the satellite communication terminal part.
The technical scheme that its technical problem that solves the utility model adopts can also be further perfect.The mobile satellite communications device generally adopts the three-axis stabilization mode, promptly by the SERVO CONTROL of orientation, pitching, three axles of roll, reaches the purpose of antenna automatic tracking satellite at the volley.Theoretically, orientation, pitching, three axles of roll are mutually orthogonal, and intersect at a point, and are optimal states.In order to realize this point, servo segment of the present utility model has adopted U type crossbeam, guarantees that so promptly orientation, pitching, three axles of roll are orthogonal to a bit, is easy to arrange rearmounted feed again.Specifically, the principal reflection body of antenna and the two ends of U-girder are hinged, and form pitch axis by the U-girder two ends; The stage casing of U-girder and pillar are hinged, and form the roll axle by the U-girder symmetry axis; Vertical axis by the base center forms azimuth axis; Pitch axis, roll axle and azimuth axis meet at a bit.Between the principal reflection body and U-girder of antenna, form a cavity, rearmounted transmission duplex feeder line and low noise amplifier are arranged in the cavity.
The effect that the utility model is useful is: the mobile satellite communications problem that 1, has solved extra small bore; 2, reduce feed part blocking to antenna reflective face; 3, receiving and transmitting signal high-gain, low secondary lobe and cross polarization isolation height have solved interference problem, guarantee communication quality; 4, manufacturing cost and use cost are low.
