Be example with the first feeder network 5a, when the grade that provides as the utility model embodiment differs branch beam-forming device feed, signal is 20 inputs from the input port, from delivery outlet 21,22,23,24,25 outputs, when all dielectric sheets 6 move to the top of medium substrate 3 with pull bar 10, the first fixed transmission lines 51a, the variable anticipating signal variable quantity at the second fixed transmission lines 51b two ends and the 3rd fixed transmission lines 51c, the variable delay signal variable quantity at the 4th fixed transmission lines 51d two ends equates, be that signal can produce a differential phase+△ respectively during through the first fixed transmission lines 51a or the second fixed transmission lines 51b, signal can produce an opposite differential phase-△ during through the 3rd fixed transmission lines 51c or the 4th fixed transmission lines 51d.
So, from the input port 20 to the transmission signal of delivery outlet 21 successively through the second fixed transmission lines 51b and the first fixed transmission lines 51a, produce the differential phase of+2 △;
From the input port 20 to the transmission signal of delivery outlet 22 through the second fixed transmission lines 51b, the differential phase of generation+△;
23 transmission signal is not through crossing fixed transmission lines 51 from input port 20 to delivery outlet, and the differential phase of generation is 0;
From the input port 20 to the transmission signal of delivery outlet 24 through the 3rd fixed transmission lines 51c, the differential phase of generation-△;
From the input port 20 to the transmission signal of delivery outlet 25 successively through the 3rd fixed transmission lines 51c and the 4th fixed transmission lines 51d, produce the differential phase of-2 △.
Accordingly, principle and the first feeder network 5a of second feeder network 5b generation differential phase are similar, do not repeat them here.
Therefore, when the grade of the utility model embodiment differ the output port 21,22,23,24,25 or 21 of branch beam-forming device ', 22 ', 23 ', 24 ', 25 ' respectively when connecting five dual-polarized antenna radiation units (not being shown among the figure) and forming antenna for base station, by pull bar 10 with moved further dielectric sheet 6, the phase of input signals generation linear change of corresponding radiating element, thereby the function of realization antenna beam electrical down-tilting.
The above embodiment has only expressed preferred implementation of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
