Abstract
A mobile satellite communication device mainly consists of antenna feeder part, servo part, monitor part and satellite communication terminal part. The antenna feeder part comprises an antenna, corrugated horn feed source, duplexer feeder line and low noise amplifier; servo part comprises beam, support column and base; the antenna comprises a main reflector, a pair of assistant reflectors oppositely disposed with the main reflector; the corrugated horn feed source faces reflecting surface of assistant reflector and is connected with the duplexer feeder line; the duplexer feeder line and low noise amplifier are disposed at back of main reflector of antenna; low noise amplifier is connected with the duplexer feeder line and connected with satellite communication terminal part; the mobile satellite communication device can reduce blocking of feeder source to reflecting surface of antenna, guarantees communication quality and relatively low cost.
Description
Technical field
The utility model relates to especially a kind of mobile satellite communications device that is applicable to the extra small bore of mobile vehicles such as car, ship of communication field j.。
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.
Present 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.
The utility model content
The utility model main purpose is to address the above problem, and 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.
In order to achieve the above object, the technical scheme that the utility model provides is: a kind of 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 of a pair of and 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.
Crossbeam in the servo segment is a U-shaped; The principal reflection body of antenna and the two ends of U-girder are hinged, the pitch axis that is formed by the U-girder two ends; The stage casing of U-girder and pillar are hinged; The roll axle that forms by the U-girder symmetry axis; The azimuth axis that forms by the vertical axis at base center; 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:
1, solved the mobile satellite communications problem of extra small bore;
2, increased by one and tackled reflector, reduced feed part blocking 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.
