Description
Technical field
This utility model is related to a kind of compact linear polarization tracker in satellite communication antena technical field, and in particular to
A kind of compact conformation, the Waveguide polarization tracker for realizing mobile vehicle satellite communication antena passive line polarization tracking.
Background technology
With the application day of the mobile vehicle satellite communication antenas such as the development of communication technology of satellite, vehicle-mounted, airborne or boat-carrying
It is beneficial extensive.Satellite communication antena was moved with the mobile vehicle moment, due to immobilizing for satellite antenna linear polarization angle, in order to ensure
During satellite communication antena linear polarization receiving and transmitting signal, antenna polarization angle is matched with the polarizing angle of satellite antenna all the time, it is to avoid
Because the energy loss that polarization adaptation is caused, it is desirable to which satellite communication antena linear polarization angle can rotate at any time, compensate due to carrying
The relative change of polarisation angles that body movement brings.
In Practical Project, for reflector antenna, linear polarization is realized typically by rotating linear polarization feed network and is tracked,
But for the flat plate array antenna being widely used at present, said method obviously has no way of implementing, for circular or sub-circular
Flat plate array antenna, can realize that by rotating whole flat plate array linear polarization is tracked, but whole antenna structure will be extremely complex；
For the flat plate array antenna with certain length-width ratio, rotating change spatially that whole flat plate array causes obviously cannot be by
Receive, so the linear polarization tracks of device that design can be used for carrier satellite communication antena, particularly flat plate array antenna becomes
The key of restriction associated antenna polarisation development.
Currently, linear polarization tracks mainly active and passive two kinds of implementations.Active linear polarization tracking, principle are simple,
The tracking time is short, but is only capable of realizing for the tracking for receiving frequency range linear polarization signal, and the key such as system standing wave, isolation refers to
Mark cannot be directly tested by instrument, and passive line polarization tracking, particularly waveguide wire polarization tracking device are because its docking sending and receiving
The features such as universality of radio band and low-loss, high-power, testability, gradually replace based on active linear polarization tracks into
Stream.

Topic is found in practical engineering application, even if the phase place of two output ports of the orthomode coupler of above-mentioned utility model
It is poor very well, if the phase contrast in two ports of flat plate array antenna which connects is larger, equally can be in polarization tracking device
Cavity underexcitation contrapolarization signal, although energy is very weak, but if contrapolarization signal can not be absorbed, the impact for bringing is,
During polarization tracking, the angle of different frequency polarization tracking device rotations is different, and for certain satellite is forwarded
Device antenna, in whole working band, the polarizing angle of all frequencies is changeless, and this will be significantly greatly increased polarization tracking device servo
The design difficulty of system simultaneously affects communication efficiency.
