Below with reference to accompanying drawings preferred implementation of the present disclosure is described in more detail.Although show preferred implementation of the present disclosure in accompanying drawing, but should be appreciated that, the disclosure can be realized in a variety of manners and not should limit by the execution mode of setting forth here.On the contrary, provide these execution modes to be to make the disclosure more thorough and complete, and complete for the scope of the present disclosure can be conveyed to those skilled in the art.
Fig. 1 is the phase shifting equipment explosive view according to the utility model embodiment.
As shown in Figure 1, phase shifting equipment comprises: pull bar 1, two fixed parts 2, two head substrates 3, two bottom substrates 5 and ground plate 6, wherein, head substrate 3, bottom substrate 5 constitute phase-shifting unit, that is phase shifting equipment contains two phase-shifting units being distributed in the upper and lower both sides of ground plate, and each phase-shifting unit can comprise at least one phase shifter.
Particularly, two bottom substrates 5 lay respectively at the both sides of ground plate 6, and are electrically coupled to ground plate 6, and two bottom substrates 5 also comprise signal input line and phase shift signal output line (not shown); Two head substrates 3 lay respectively at the both sides of two bottom substrates 5, and namely head substrate 3, bottom substrate 5 and ground plate 6 set gradually; Pull bar 1, thus can simultaneously and adjust the phase place of each phase-shifting unit output signal with contrary phase place variation tendency for regulating the relative sliding between head substrate and two bottom substrates.
Fig. 2 is the bottom substrate of foundation the utility model embodiment and the simple schematic diagram of head substrate.Bottom substrate 5 arranges at least one signal input line and at least one phase shift signal output line towards the side of head substrate 3, such as, be respectively a signal input line 52 and three phase shift signal output line 53-55.Head substrate is provided with at least one U-shaped line towards the side of bottom substrate, for example two U-shaped lines 32,33, when bottom substrate and head substrate are in time even fitting, even if its surface coverage has insulating barrier, the signal between two substrates also can be transmitted by coupled modes.Therefore, two U-shaped lines in figure achieve two phase shifters, and that is, phase-shifting unit contains two phase shifters.Be understandable that Fig. 2 all details of not shown bottom substrate and head substrate illustrate only the part relevant to signal coupling.
Preferably, bottom substrate 5 and the position except welding on head substrate 3, other position is all covered with insulating barrier, such as liquid photopolymerizable solder resist (green oil).
Please still consult Fig. 1, in the present embodiment, fixed part 2 is for interfixing two head substrates 3 being positioned at ground plate 6 both sides.Fixed part 2 is also coupled to pull bar 1, thus when pull bar 1 carries out side-to-side movement, it moves driving the head substrate 3 being distributed in ground plate 6 both sides with same direction.
Preferably, fixed part 2 comprises two can the first firmware of fastening and the second firmware mutually, when first, second firmware fastening, head substrate and bottom substrate fit or between leave less gap.Particularly, first firmware is provided with at least one rivet 21 and at least one groove, second firmware is provided with accordingly at least one rivet 21 and at least one groove, thus between the first firmware and the second firmware can by rivet and groove match form a fixed connection.Correspondingly, head substrate 3 is provided with at least two through holes 31, passes for the rivet 21 on first, second firmware described, thus be fixed.Bottom substrate is also provided with at least one elongated hole, such as two elongated holes 51, for providing the space of the rivet 21 on first, second firmware.That is, the rivet 21 on the first firmware, by successively through through hole 31, elongated hole 51 and elongated hole 61 and then elongated hole 51, through hole 31 through opposite side, finally plugs together with the groove on the second firmware, to form a fixed connection mutually.When pull bar 1 carries out side-to-side movement, the head substrate 3 of both sides with the motion of same direction, and is in elongated hole 51 and 61 due to rivet, and therefore, frictional force of its motion is very little.
In order to make to keep between bottom substrate 5 with ground plate 6 being fixedly connected with and relative displacement not occurring, therefore, phase shifting equipment also comprises plate and connects rivet 7.This plate is connect rivet 7 and two bottom substrates and ground plate is interfixed with the through hole 62 be arranged on ground plate by the through hole 56 be arranged on two bottom substrates 5.
Fig. 3 is the phase shift signal schematic diagram of the antenna according to the utility model embodiment.

When this phase shifting equipment uses in antennas, need to the signal after its input signal and its phase shift of reception, therefore, as shown in Figure 1, cable 8-11 is coupled to respectively by coupling block 4 signal input line 52 and three phase shift signal output line 53-55 that bottom substrate 5 is arranged.Corresponding, cable 8,12-14 are coupled to signal input line on another bottom substrate 5 and three phase shift signal output lines respectively.
In addition, connected by cable 9,10, cable 12,13 connects, thus forms corresponding C4 and C6 respectively.
When pull bar 1 drives upper and lower two pieces of head substrates to move in the same direction, the transmission path of obvious signal between upper and lower two pieces of head substrates and two pieces of bottom substrates creates change, namely large one an of change diminishes, thus makes the phase difference variable between C3 and C7 large, therefore, the present embodiment is by the setting of upper and lower two-layer substrate, make head substrate only need mobile very little distance, just can reach the effect changing phase difference, therefore, phase shifting equipment can do relatively little, to save cost.
Preferably, above-mentioned fixed part 2 and/or plate connect rivet 7 and are made up of nonmetallic materials, so can promote the PIM performance of phase shifting equipment.Here nonmetallic materials can be plastics, rubber etc.
View before Fig. 4 a slides after showing the phase shifting equipment assembling according to the utility model embodiment, the view after Fig. 4 b slides after showing the phase shifting equipment assembling according to the utility model embodiment.
Obviously, driven the motion of head substrate 3 by pull bar 1, obviously can change the path-length of signal, thus can by only sliding less distance, just can at the larger phase difference of the realization of phase shifting equipment the right and left.
The utility model also proposed a kind of electrical tilt antenna, comprise: this antenna comprises aforesaid phase shifting equipment and ACU, wherein, ACU is coupled to pull bar 1, for driving pull bar 1, and then two head substrates can side by side be slided by relative two bottom substrates, thus larger phase difference can be realized with less sliding stroke.
