In order to make the network layout of the integrated phase shifter more reasonable, and the lines are simple and small in number, referring to the schematic structural diagram of the integrated phase shifter shown in fig. 2, it is preferable that the connection line 14 connecting the first input port 131 of the combiner and the branch feed port 111 of the first phase shifter is arranged at the designated position 15 by means of staggered routing; a connecting line connecting the second input port 132 of the combiner and the branch feed port 111 of the second phase shifter is arranged at the designated position 15 in a staggered routing manner; wherein the designated location 15 comprises a location of a cross-track.
A conventional phase shifter includes a main feed port, such as the schematic structure of the phase shifter shown in fig. 3, which includes six branch feed ports 111 and a main feed port 112; the main feed port needs to be electrically connected with external equipment, a connecting line connected with the main feed port 112 of the first phase shifter, and a connecting line connected with the first input port 131 of the combiner and the branch feed port 111 of the first phase shifter need to be crossed and wired; in addition, the connection line connected to the main feed port 112 of the second phase shifter and the connection line connected to the second input port 132 of the combiner and the branch feed port 111 of the second phase shifter need to be crossed; therefore, the connecting lines at the crossed wiring positions are arranged in a staggered wiring mode, the number of cables can be reduced, complicated cable wiring is avoided, and the integrated phase shifter is simple in layout on the whole antenna.
Further, referring to the schematic structural diagram of the integrated phase shifter shown in fig. 4, wherein the first phase shifter 11, the second phase shifter 12, the plurality of combiners 13, and the plurality of connection lines 14 are disposed on the PCB substrate 100; the arrangement position of the phase shifter and the combiner on the PCB is not limited to the arrangement in fig. 3.
In the above staggered routing manner, referring to the schematic diagram of staggered routing shown in fig. 5, two metal vias 151 are included on the PCB substrate corresponding to the designated position 15; the metal via 151 is used for leading the connecting line 14 at the designated position 15 to the isolation groove 152 of the PCB substrate; an isolation layer (not shown) is disposed in the isolation groove, and the isolation layer is located between the connection line at the designated position and the ground layer of the PCB substrate.
A metal via hole 151 is arranged on the branch feed port of the first phase shifter 11, the second phase shifter 12 and the combiner 13 working at the same frequency band, a connecting line is led to a ground layer on the back of the PCB substrate corresponding to the designated position 15 through the metal via hole 151, an isolation groove 152 is arranged on the ground layer, a planar transmission connecting line is arranged in the isolation groove, the connecting line is led to the upper layer of the PCB substrate corresponding to the designated position through another metal via hole 151, and the connecting line is electrically connected with the input port of the frequency band corresponding to the combiner 13; in addition, a narrow slit is arranged between the plane transmission connecting line arranged in the isolation groove and the ground layer of the PCB substrate, and the narrow slit can isolate the transmission signal of the plane transmission connecting line from the signal of the ground layer on the back surface of the PCB substrate.
The combiner 13 further includes an output port 133; the connecting line 14 includes a microstrip line; the first phase shifter includes a main feed port; the second phase shifter includes a main feed port; for each combiner, the difference value between the first electrical length of the microstrip line connecting the main feed port of the first phase shifter and the output port of the combiner and the second electrical length of the microstrip line connecting the main feed port of the second phase shifter and the output port of the combiner is the same.
The electrical length is generally referred to as the ratio of the physical length of the microstrip transmission line to the wavelength of the electromagnetic wave being transmitted. Specifically, the connecting lines 14 between the first phase shifter and the combiner and between the second phase shifter and the combiner are implemented in a microstrip line connection manner, wherein the electrical lengths of the connected microstrip lines need to be matched, and the purpose of phase matching is to ensure that the lengths of cables externally connected to the same output port of the integrated phase shifter working in two different frequency bands are kept consistent. The method can be implemented by adjusting the electrical length of the microstrip line from the main feed port 112 of the first phase shifter 11 working in one frequency band to the output port 133 of each combiner 13, and keeping the difference between the electrical lengths of the microstrip line from the main feed port 112 of the second phase shifter working in another frequency band to the output port 133 of each combiner 13 consistent, so that the lengths of the external cables of the same output port are the same when the two phase shifters in the integrated phase shifter 1 work in two different frequency bands. It can be understood that the phase of the main feed port 112 of the first phase shifter 11 operating in one frequency band to the output port 133 of the combiner 13 is adjusted by changing the electrical length of the microstrip connection line, and the difference of the phase of the main feed port 112 of the second phase shifter 12 operating in the other frequency band and the output port 133 of the combiner 13 is maintained to be the same.
Of course, it can also be understood that, for each combiner, the phase of the connection line from the main feed port of the first phase shifter to one of the branch feed ports of the first phase shifters, plus the first phase sum of the phases of the connection lines from that branch feed port to the output port of the combiner connected to that branch feed port; a phase of a connection line from a main feed port of the second phase shifter to one branch feed port in the second phase shifter, plus a second phase sum of phases of connection lines from the branch feed port to an output port of a combiner connected to the branch feed port; the difference between the first phase sum and the second phase sum is kept the same.
Referring to the schematic structural diagram of the combiner shown in fig. 6, the first input port 131 and the second input port 132 of the combiner are located on the same side of the combiner; the output port 133 of the combiner is located at the other side corresponding to the first input port 131 and the second input port 132;
for example, fig. 4 shows a schematic structure of an integrated phase shifter, in which a first phase shifter 11 and a second phase shifter 12 are arranged in a vertical direction; the first phase shifter and the second phase shifter have the same structure; the plurality of combiners are respectively positioned at two sides of the first phase shifter and the second phase shifter.
In this embodiment, the first phase shifter and the second phase shifter have the same structural form, and referring to the structural schematic diagram of the integrated phase shifter shown in fig. 4, a phase shift film 113 covers a line where a branch feed port and a main feed port of the phase shifter are located, a coupling power division line is disposed on one side of the phase shift film close to the phase shifter PCB substrate 100, the coupling power division line is connected to the main feed line of the phase shifter at a rotation axis of the phase shift film 113, an amplitude and a phase shift amount required by each branch feed port 111 of the phase shifter are obtained by rotating an angle of the phase shift film, and the amplitude and the phase shift amount obtained by different branch feed ports 111 are different, thereby achieving adjustment of the antenna beam down tilt.
In addition, a plurality of combiners are respectively disposed at two sides of the first phase shifter and the second phase shifter, and generally, an integrated phase shifter includes a plurality of combiners, and each combiner may be respectively disposed at two sides of the first phase shifter and the second phase shifter according to the number and size of the combiners.
In order to integrate the integrated phase shifter on the PCB substrate, and to make the network layout of the integrated phase shifter more reasonable and the size more compact, the layout of the integrated phase shifter may be such that a plurality of combiners 13 connected to the branch feed ports on the same side of the first phase shifter 11 and the second phase shifter 12 are sequentially arranged from inside to outside; wherein the size of the externally located combiner 13 is larger than the size of the internally located combiner 13.
Specifically, referring to the schematic structural diagrams of the integrated phase shifter shown in fig. 2 and fig. 4, in this embodiment, the structural form of the combiner 13 is a "U" shape, that is, two input ports of the combiner 13 are located on the same side, and the output end of the combiner 13 is located on the other corresponding side. The size of the combiner 13 connected to the branch feed ports on the same side of the first phase shifter 11 and the second phase shifter 12 is sequentially set from small to large, and a layout form in which the small-sized combiner 13 is enclosed by the large-sized combiner 13 is adopted.
In this embodiment, the number of the corresponding combiners 13 is six, each combiner is located on two sides of the first phase shifter 11 and the second phase shifter 12, the number of the combiners 13 on each side is three, the first input port 131 and the second input port of each combiner 13 correspond to the same frequency band of the operation of the first phase shifter 11 and the second phase shifter 12, and the first input port and the second input port of each combiner 13 are electrically connected through the phase shifter and the connecting line 14 between the combiners.

the output port 133 of the small-sized combiner 13 enclosed by the large-sized combiner 13 is connected to an external cable and needs to be extended in a cross-routing manner, that is, the output port 133 of the small-sized combiner 13 is led out in a staggered cross-routing manner to be used as an output port of the integrated phase shifter 1 and electrically connected with the outside. By adopting the method, the network layout of the integrator phase shifter can be more reasonable, and the size is more miniaturized.
Further, the number of the combiners 13 is the same as the number of target feeder ports in the first phase shifter 11 or the second phase shifter 12; the target feeder port includes a feeder port that is not connected to an external device.
In this embodiment, the first phase shifter 11 and the second phase shifter may further include a main feed port, three branch feed ports, a main feed port, four branch feed ports, a main feed port, five branch feed ports, a main feed port, seven branch feed ports, and other multiple forms. And the number of the corresponding combiners 13 is set according to the number of the branch feed ports of the first phase shifter 11 and the second phase shifter 12, and is set according to the way in which the branch feed ports of the first phase shifter 11 and the second phase shifter 12 are electrically connected to the outside; for example, the first phase shifter and the second phase shifter respectively include five branch feed ports, wherein the main feed ports of the first phase shifter and the second phase shifter are electrically connected to the outside, one main feed port of the first phase shifter is electrically connected to the outside, and one main feed port of the second phase shifter is also electrically connected to the outside, and at this time, 4 branch feed ports of the first phase shifter or the second phase shifter are provided, and the number of combiners can be determined to be 4.

In this embodiment, the first phase shifter and the second phase shifter have different operating frequency bands.
The integrated phase shifter integrates the combiner and two phase shifters working at different frequency bands into one PCB substrate, and two input ports of the combiner are electrically connected with the branch feed ports of the two phase shifters working at different frequency bands respectively in a staggered cross wiring mode to be integrated together, so that the two phase shifters working at different frequency bands and the combiner can be integrated into a whole without coaxial cable connection, the number of cables is greatly reduced, complicated cable wiring is avoided, and the integrated phase shifter has the advantages of simple spatial layout, few welding spots and high producibility. And the structure size is miniaturized, and the cost is low.
