Between isolation.Those skilled in the art know, for an antenna 1, according to its specific wave beam
Reclining angle, can only obtain under this angle most preferably or preferably isolation, therefore, even if antenna 1 wave beam
Reclining angle can be increased or decreased, but the isolation change caused by the azimuth shift of decoupling cell 3
May be only to ensure that it keeps the isolation before not shifting, be not necessarily enhanced or reduce, accordingly,
Feed-in port 41, the electromagnetic field couples between 42 also might not be further augmented or reduce, and technology is real
Existing target is still to keep the electromagnetic field of minimum or relatively low (requiring in the range of permission at technical parameter)
Coupling, to guarantee the highest or higher isolation, is to maintain rather than improves or reduce.More very, ability
When field technique personnel are it is to be understood that decoupling cell 3 is shifted, even if produce sky due to physical control
Right physical error, causes feed-in port 41, and the electromagnetic field couples between 42 is decreased or increased by trace,
Also should be considered to maintain minimum or relatively low electromagnetic field couples and the highest or higher isolation, must regard
Within occuping the spirit of the present invention.
Visible, the first embodiment of the present invention, by regulation parts 2 execute control, can realize move
While changing antenna lower decline angle, the orientation that synchronous change decoupling cell is occupied, in this enforcement
Example mainly shows as the decoupling cell 3 shifting for metallic reflection plate 10 on its horizontal level
Position regulation, in order to no matter finally realizing how antenna beam reclining angle changes, all can synchronous change uncoupling

The rotating speed of regulation parts 2, and the rate travel of the movable part 93 of described phase shifting equipment, and described
The rate travel of decoupling cell 3, all can be different, the need designed antenna 1 depending on those skilled in the art
Ask and determine flexibly.Hereinafter by other embodiments, this principle will be illustrated.
Refer to the 3rd embodiment disclosed in Fig. 5, relative to first embodiment, torque transmitting therein
Mechanism sets up a moment converting unit further, and this moment converting unit includes the first tooth bar 51, driven tooth
Wheel the 52, second tooth bar 54 and support guide rod 50, described first tooth bar 51 is fixedly connected on described moment
On one local location of the drive link 32 of transmission mechanism, described support guide rod 50 and this torque transmitting machine
The drive link 32 of structure be arranged in parallel, and support guide rod 50 is generally U-shaped, and its two-arm is separately fixed at metal
Reflecting plate 10, described second tooth bar 54 is set on the middle sliver of this support guide rod 50, in order to second
Tooth bar 54 can slide along this middle sliver, and the second tooth bar 54 is also fixedly installed described uncoupling list
Unit 3.Between described first tooth bar 51 and the second tooth bar 54, it is equipped with and is articulated on metallic reflection plate 10
Described driven gear 52, this driven gear 52 respectively with described first tooth bar 51 and the second tooth bar 54
It is meshed.Thus, when the drive link 32 of torque transmission mechanism is driven, its in the future self-regulation parts 2
Moment through self passing to the first tooth bar 51, the first tooth bar 51 by with driven gear 52 engage pass
System, drives driven gear 52 to rotate, driven gear 52 and then by nibbling between itself and the second tooth bar 54
Conjunction relation, gives the second tooth bar 54 and decoupling cell 3 by torque transmitting again, so that decoupling cell 3
Under the drive of the second tooth bar 54, the middle sliver along described support guide rod 50 does direct back and forth movement.
Obviously, although be all straight line back and forth movement, but due to the back action of driven gear 52, uncoupling list
Unit the direction of motion of 3 be contrary with the direction of motion of described drive link 32, both forms of motion just in
Existing difference.
Refer to the 4th embodiment disclosed in Fig. 6.Aforementioned disclose the second embodiment time address change in passing
Speed mechanism application in the present invention, the embodiment disclosed in Fig. 6 just implements this application, its based on
Structure disclosed in Fig. 5, changes moment conversion by increasing a less driving gear 53 of radial dimension
The concrete structure of unit, achieves the motion of speed change and break-in, specifically relative to the 3rd embodiment:
On the basis of the structure of the moment converting unit disclosed in the 3rd embodiment, increase described support guide rod 50
