Background technique

In mobile communication, signal coverage optimization is implemented to suppress signal interference to neighboring cells, and an electrical adjustment antenna is used. The phase shifter is an essential part of the ESC antenna. Most of the existing phase shifters are implemented by the method of medium loading.

The inventors have found that the prior art media phase shifter network layout has the following problems:

1. The length is relatively long, for example, the medium phase shifter of patent number CN102544733B, the phase shifter is a series structure, and the phase shifting branches are arranged longitudinally, and the phase shifter is large in volume and long in length.

2. The setting of the relative position of the output port and the radiating element of the phase shifter is not optimal. The phase shifter of the patent number CN103199322B has a long physical distance between the maximum phase shifting port and the antenna radiating element, resulting in a corresponding cable length of the other ports of the phase shifter. Increasing, the cable length of the antenna is too long, which affects the gain performance of the antenna.

Summary of the invention

The invention provides a phase shifter and an antenna, which solves the problem that the existing phase shifter is bulky and long in length. At the same time, the order of the output ports of the phase shifters is optimized, so that the cable length connecting the output ports of the phase shifters to the radiating elements is the shortest, and the antenna gain is improved.

The invention provides a phase shifter comprising an input port, a power splitter, a phase shifting branch, an output port and a medium slider, wherein the phase shifting branch and the power splitter together form a feeding line, and the medium slider is provided with an adjustment matching The opening is arranged such that the medium slider and the feeding line slide relative to each other along the AA direction, and the direction perpendicular to the AA direction is recorded as the BB direction, and two columns or more are extended along the AA direction on the left side and/or the right side of the input port.

Moreover, the output port with a larger phase change is farther away from the input port.

Also, the left and right sides of the input port are symmetrically set.

Moreover, it includes ten phase shifting branches and seven power splitters, centered on one-third of the main power splitter, and other power splitters are symmetrically set about the main power splitter, and three are set left and right respectively; The main power divider is symmetrically set to the left and right, and each of the left and right sides is five; after pulling the medium slider to slide, the ratio of the phase changes of the nine output ports before the medium is pulled is

Moreover, it includes eight phase shifting nodes and five power splitters, centered on one-third of the main power splitter, and other power splitters are symmetrically set about the main power splitter, and two are set left and right respectively; the phase shifting section is about The main power splitter is symmetrically set to the left and right, and each of the left and right sides is four; after pulling the medium slider to slide, the ratio of the phase changes of the seven output ports before the medium is pulled is

Moreover, it includes ten phase shifting branches and three power splitters, centered on one-third of the main power splitter, and the other power splitters are symmetrically arranged on the left and right sides of the main power splitter, and one is set left and right; the phase shifting section is about the main The power splitter is symmetrically set to the left and right, and each of the left and right is five; after pulling the medium slider to slide, the ratio of the phase changes of the five output ports before the medium is pulled is

Or, the left and right sides of the input port are asymmetric settings.

Moreover, the output ports on the left and right sides of the input port are even-numbered and have a difference of one.

The invention also provides an antenna comprising the phase shifter described above.

The phase shifter and the antenna provided by the present invention have the following advantages by providing a phase shifting node:

1. The combination of series feed and parallel feed reduces the length of the phase shifter.

2. The output ports of the phase shifters are arranged in order according to the magnitude of the phase change, and the order of the ports is not crossed. The output port of the maximum phase shifting quantity is close to the radiation element of its corresponding connection, which reduces the cable length connecting the output port of the phase shifter and the radiating element, so as to avoid the occurrence of the maximum phase shifting port and the corresponding radiation element in the prior art. And causing the connection cable If it is too long, the gain of the antenna will be increased.

3. The cable bending direction and bending radius of each port of the phase shifter are small and the phase consistency is high, which improves the reliability of the antenna system and the consistency of mass production.

The phase change of the port 1017 is connected in series with a phase shifting node 302a based on the phase change of the port 1016, and the phase change of the port 1016 and the port 1017 is in a series relationship.

After the input signal passes through the input port 100, the first phase shifting node 301a, the power splitter 102a, the third phase shifting node 303a, the fourth phase shifting node 304a, and the phase change of the port 1018 are

After the input signal passes through the input port 100, it passes through the first shifting node 301a, the power splitter 102a, and then passes through the third shifting node 303a, after passing through the fourth shifting node 304a, the power splitter 104a, and then the fifth. Phase shifting branch 305a, phase change of port 1019 is

The phase change of the port 1019 is connected in series with a phase shifting node 302a based on the phase change of the port 1018, and the phase change of the port 1019 and the port 1018 is in a series relationship.

Port 1019 and port 1018, port 1017 and port 1016 share a first phase shifting node 301a, the phase change is a synchronous change, and the

ports

1019, 1018 and

ports

1017, 1016 are phase-changed in a parallel relationship.

After the input signal passes through the input port 100, after the first phase shifting node 301b, the transmission line segment 501b, and the power divider 103b, after the output port 1011, the phase changes to

The farther the phase change is, the further the physical distance from the input port 100 is.

The port arrangement is more reasonable than the prior art of patent number CN103199322B. Since the most preferred solution for the port layout of the phase shifter is the farther away from the vibrator, the phase shift port phase changes the most. It is best not to have the quadruple port closest to the vibrator with one phase change, so that the total cable length will increase and the gain loss will be large. The patent CN103199322B cable must cross, and the total cable length of the antenna machine must not be optimal. Although the phase shifter is small, the gain is likely to be consumed on the cable, and the gain loss is too large.

Figure 3 is a schematic illustration of a phase shifter coupled to an antenna radiating element. It can be seen that the bending of the cable does not cross, and the difference between the bending radius and the bending direction of the cable is small, the phase consistency is high, the reliability of the antenna system and the consistency of production are improved; and the port with the largest phase change is away from the corresponding radiating element. The physical distance is the shortest, and the length of the RF cable of each output port of the phase shifter to the radiation element is reduced as a whole, and the gain performance of the whole antenna is improved.

A phase shifter having this phase change relationship can be applied to antennas of nine, ten, eleven or thirteen radiating elements, each of which can be connected to one or more radiating elements.
