See also Fig. 3, Fig. 5 and Figure 10, for first dielectric-slab 430 and second dielectric-slab 440 are moved along conduction band 412a, 414a, 412b, 414b and phase shift band 433 respectively, phase shift mechanism 40 also has a plurality of guide plates 450, guide plate 450 is rectangle, its edge offers and is provided with chute 451, thereby forms a slide rail (among the figure not label).In the present embodiment, totally 6 on guide plate 450, per two guide plates, 450 stacked settings also are fixed on the base plate 110 of reflecting plate 10, and these two guide plates 450 close with corresponding first dielectric-slab 430 or second dielectric-slab, 440 ranks respectively, the slide rail of guide plate 450 is stretched in the guide groove 442 of the guide groove 434 of first dielectric-slab 430 or second dielectric-slab 440, the guide rail of first dielectric-slab 430 or the guide rail of second dielectric-slab 440 are stretched in the chute 451 of guide plate 450, smoothly move thereby guide first dielectric-slab 430 or second dielectric-slab 440.
See also Fig. 1, Fig. 2 and Fig. 5, governor motion 50 has a driver element 510, a driven unit 520 and a linkage unit 530.Driver element 510 has a driving shaft 511, and is fixed on driving gear 512, a housing 513 and two pivotal blocks 514 on the driving shaft.Housing 513 roughly is " ㄩ " shape, its two ends are separately fixed on the side plate 120 of reflecting plate 10, and offer an axis hole 515 on the housing 513, the base plate 110 that two pivotal blocks 514 are fixed on reflecting plate 10 is provided with a side of array 20 and is positioned at the both sides of slotted eye 150, driving shaft 511 is articulated on two pivotal blocks 514, and an end of driving shaft 511 passes the axis hole 515 of housing 513.Driving gear 512 is between two pivotal blocks 514, and its part is passed the slotted eye 150 of base plate 110.
Adjusting rod 531 is screwed onto on the screw rod 521 by screwed hole 533, and this adjusting rod 531 is between driven gear 522 and position limitation protection cover 524.The two ends of fixed lever 532 are formed with fixture block 535.The fixture block 535 of different fixing bar 532 snaps in respectively in the bayonet socket 441 of block button hole 534, first dielectric-slab, 430 bayonet sockets 433, second dielectric-slab 440 of adjusting rod 531, thereby first dielectric-slab 430, second dielectric-slab 440 and adjusting rod 531 are connected as a single entity, therefore can make first dielectric-slab 430 and second dielectric-slab, 440 same moved further.
See also Fig. 3 and Fig. 4, the signal of telecommunication is after feeding portion 421 feed-ins, the part of the signal of telecommunication is through the dual polarization oscillator 210 in the middle of 422 feed-ins of signal band, another part of the signal of telecommunication is divided into behind the two paths of signals feed-in corresponding first respectively through two phase shift bands 433 and presents the transport tape 413 of strip line 410, and the signal of feed-in transport tape 413 is divided into five road signals through conduction band 412a, 414a, 412b, 414b, 412c and the corresponding dual polarization oscillator 210 of feed-in respectively.
When adjusting phase shift mechanism 40 transfers the angle of declination of antenna for base station to change the integrated electricity of the present invention, the driving shaft 511 that drives governor motion 50 by manual or electronic mode rotates, thereby driving gear 512 drives driven gear 522 and rotates, and then driven gear 522 drives that screw rods 521 rotate so that screw rod 521 promotes adjusting rods 531 moves, thus fixed lever 532 drive first dielectric-slabs 430 and second dielectric-slab 440 under the guiding of guide plate 450 respectively along first and the phase shift band 433 of presenting conduction band 412a, 414a, 412b, 414b and second dielectric-slab 440 of strip line 410 move.
When second dielectric-slab 440 moved along two phase shift bands 433, because the bearing of trend of two phase shift bands 433 is opposite, the phase place of the two paths of signals that is divided through two phase shift bands 433 was changed to respectively
One first and the signal of presenting strip line 410 of feed-in phase-shifting unit 400 divide the phase place of five road signals to be changed to respectively through conduction band 412a, 412b, 412c, 414b, 414a
Feed-in phase-shifting unit 400 another first and the signal of presenting strip line 410 divide the phase place of five road signals to be changed to respectively through conduction band 414a, 414b, 412c, 412b, 412a
Therefore the phase change of 11 dual polarization oscillators 210 is followed successively by
