[0034] Phase shifter: the phase shifter is an important device for electrically adjusting the downtilt angle in the base station antenna. In the mobile communication system, in order to optimize the coverage of wireless signals in the service area, and to suppress the mutual interference of signals of the same frequency, it is necessary to reasonably adjust the downtilt angle of the base station antenna. The phase shifter continuously adjusts the feed network of the antenna, continuously changes the phase of each radiation unit in the antenna array, so as to realize the continuous adjustment of the electric downtilt angle of the antenna under the premise that the physical position of the antenna is unchanged.

[0035] With the progress of electronic product technology, multi-frequency multi-port electrically adjustable antennas are developing towards integration, miniaturization, low cost and light weight, which makes the available space inside the antenna smaller and smaller. The application aims to provide a combining and phase-shifting device, which concentrates the dispersed combiners and phase shifters together, can optimize the internal space of the antenna, improve the integration of the overall design, and is conducive to production and assembly.

In the application, the first phase shifter module, the second phase shifter module and the M first combining unit modules are all PCB board structures, that is, the first phase shifter module, the second phase shifter module and the M first combining unit modules are all located on a first PCB board. It should be noted that the first PCB board is a fixed PCB board.

[0037] Each phase shifter module comprises N first transmission lines, that is, the first phase shifter module comprises N first transmission lines, and the second phase shifter module also comprises N first transmission lines. M first transmission lines of the N first transmission lines of each phase shifter module are connected with M first combining unit modules respectively.

[0038] Optionally, in a possible implementation, the input end of the N first transmission lines corresponding to each phase shifter module is connected with the first sub-feeding port of the corresponding phase shifter module. That is, in this case, the number of first sub-feeding ports of each phase shifter module is the same as the number of first transmission lines of each phase shifter module. The first sub-feeding port is used for phase-shifting the signal input into the phase shifter module.

[0039] For example, as shown in the following Figure 1 and Figure 2 .

[0043] The phase shifter module 1 comprises six first sub-feeding ports (not shown in the figure), first transmission lines (101, 102, 103, 104, 105, 106) connected with the six first sub-feeding ports, a main input strip line 110, and a second transmission line 120. Specifically, the main input strip line 110 is coupled with the first transmission lines (101, 102, 103, 104, 105, 106) through the second transmission line 120, as shown in the figure, the second transmission line 120 is located directly above the first transmission lines (101, 102, 103, 104, 105, 106), and is coupled with the main input strip line 110 and the first transmission lines (101, 102, 103, 104, 105, 106).

The fixing member 130 rotates around the center of the second transmission line 120 as the axis to achieve the purpose of phase shifting at the six first sub-feeding ports.

[0045] The phase shifter module 2 comprises six first sub-feeding ports (not shown in the figure), first transmission lines (201, 202, 203, 204, 205, 206) connected with the six first sub-feeding ports, a main input strip line 210, and a second transmission line 220. Specifically, the main input strip line 210 is coupled with the first transmission lines (201, 202, 203, 204, 205, 206) through the second transmission line 220, as shown in the figure, the second transmission line 220 is located directly above the first transmission lines (201, 202, 203, 204, 205, 206), and is coupled with the main input strip line 210 and the first transmission lines (201, 202, 203, 204, 205, 206).

[0046] Optionally, the combining phase shift device 100 can further comprise a fixing member 230 for accommodating the second transmission line 220, or in other words, the second transmission line 220 is fixed in the fixing member 230. The fixing member 230 rotates around the center of the second transmission line 220 as the axis to achieve the purpose of phase shifting at the six first sub-feeding ports.

[0047] It should be noted that the fixing member 130 and the fixing member 230 described above can be a PCB board, or the fixing member 130 and the fixing member 230 described above can also be a plastic part, and it should be understood that the present application does not limit this.

[0048] In a possible implementation, the second transmission line 120 and the second transmission line 220 described above can be metal strip lines.

[0049] It should be noted that, in the embodiments of the present application, the first transmission line of the phase shifter module 1 and the phase shifter module 2 is located on the inner side, and the main input strip line is located on the outer side. Wherein, the first transmission line is located on the inner side, and the main input strip line is located on the outer side, which can be understood as that the position of the first transmission line relative to the main input strip line is on the inner side, and correspondingly, the position of the main input strip line relative to the first transmission line is on the outer side.

[0050] Alternatively, since the first transmission line is connected with the first branch feeding port, the above case can also be understood as that the first branch feeding port of the phase shifter module 1 and the phase shifter module 2 is located on the inner side, and the main input strip line 110 and the main input strip line 210 are located on the outer side. Wherein, the first branch feeding port is located on the inner side, and the main input strip line is located on the outer side, which can be understood as that the position of the first branch feeding port relative to the main input strip line is on the inner side, and correspondingly, the position of the main input strip line relative to the branch feeding port is on the outer side.

Or, the output port transmission line of the signal line of the i th first combining unit module in the five first combining unit modules crosses the position where the ground signal line of the other first combining unit module is located.

[0055] For example, taking i = 2 as an example, the output port transmission line of the signal line of the 2nd first combining unit module (for example, first combining unit module 4) in the 5 first combining unit modules transits through the ground signal lines of other first combining unit modules (for example, first combining unit modules 3, 5, 6, 7); for example, taking i = 2 and i = 3 as an example, the output port transmission line of the signal line of the 2nd and 3rd first combining unit modules (for example, first combining unit modules 4, 5) in the 5 first combining unit modules transits through the ground signal lines of other first combining unit modules (for example, first combining unit modules 3, 6, 7). It should be understood that the above is only an example, and the present application is not limited thereto.
