With the development of communication technology, especially the development of 5G communication technology, the combiner needs to add 5G frequency band [such as frequency band 3 (3300MHz-3800MHz)], which requires the port bandwidth of the common port of the traditional combiner to realize the combination and separation of signals between at least three different frequency bands.

It should be understood that the specific embodiments described herein are only used to explain the application, and do not limit the protection scope of the application.

When an element is referred to as being "connected" or "electrically connected" to another element, it can be directly connected to the other element or intervening elements can also be present. Further, when an element is referred to as being "connected" or "electrically connected" to another element, it can be electrically connected to the other element in a detachable manner or in a non-detachable manner such as screwing, welding, etc., which can be achieved in the prior art and will not be described here.

The terms "perpendicular", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0031] The "first", "second", "third" involved in the present application do not represent the specific number and order, but only for the purpose of distinguishing names.

[0032] When 5G is constructed, a non-independent networking mode can be used for deployment. That is, the construction of 5G can rely on the resources of the existing 4G base station to expand the network capacity and coverage of 4G. In this way, the maintenance cost of 5G and later can be saved. Therefore, the combiner used also needs to be able to meet the requirements of the 5G frequency band and be compatible with the 4G frequency band and the 2G frequency band.

[0033] However, the traditional combiner can realize the combination and separation of frequency band 1 (such as 800MHz-960MHz) and frequency band 2 (such as 1400MHz-2700MHz). However, due to the high frequency and short wavelength of the 5G frequency band (such as 3300MHz-3800MHz), the common port structure of the traditional combiner is difficult to meet the requirements.

[0034] Therefore, as shown in FIG. 1, the combiner of the present application comprises a first port 1, a second port 2, a third port 3, a fourth port 4, a fifth port 5 and a sixth port 6. Figures 1 to 4As shown, the present application provides a common port structure, comprising a cavity 100, a common joint 200, a first resonant column 300, a second resonant column 500 and a third resonant column 700; the cavity 100 is provided with a resonant cavity 110, the common joint 200 is electrically connected with a feed 210, the feed 210 is inserted into the resonant cavity 110; the first resonant column 300 is arranged in the resonant cavity 110, the first resonant column 300 is electrically connected with a first conducting band 400, the first conducting band 400 is electrically connected with the feed 210; the second resonant column 500 is arranged in the resonant cavity 110, the second resonant column 500 is electrically connected with a second conducting band 600, the second conducting band 600 is electrically connected with the feed 210; the third resonant column 700 is arranged in the resonant cavity 110 and is coupled with the first conducting band 400.

[0035] When the above common port structure is used, it is assumed that the first resonant column 300 corresponds to frequency band 1 (such as 800MHz-960MHz), the second resonant column 500 corresponds to frequency band 2 (such as 1400MHz-2700MHz), and the third resonant column 700 corresponds to frequency band 3 (such as 3300MHz-3800MHz, i.e. 5G frequency band), and then the above common port structure can realize the splitting and combining of frequency band 1 and frequency band 2 and frequency band 3. Specifically, the feed 210 is fixedly connected with the common joint 200, so that the electromagnetic field energy is radiated into the resonant cavity 110 through the common joint 200 and the feed 210, thereby realizing the distribution of the bandwidth of each frequency band; the bandwidth of frequency band 1 is realized by electrically connecting the first resonant column 300 with the first conducting band 400 and the feed 210, the bandwidth of frequency band 2 is realized by electrically connecting the second resonant column 500 with the second conducting band 600 and the feed 210, and the bandwidth of frequency band 3 is realized by capacitive coupling of the third resonant column 700 with the first conducting band 400. Then the common port structure can adapt to signals between at least three different frequency bands for splitting and combining. In addition, when bandwidth distribution is required, the common port structure of the present application can be adjusted by one or more of the feed 210, the first conducting band 400 or the second conducting band 600, that is, the port bandwidth can be adjusted, which is more convenient and flexible compared with the prior art.

[0036] It can be understood that the first resonant column 300 is electrically connected with the common joint 200 through the first conducting band 400, and the second resonant column 500 is electrically connected with the common joint 200 through the second conducting band 600, which is equivalent to inductive connection between the first resonant column 300 and the common joint 200, and between the second resonant column 500 and the common joint 200. The port bandwidth is adjusted by inductive connection, so that the position of the common joint 200 can be flexibly set, and the realization is simpler and more convenient. At the same time, the bandwidth of frequency band 3 is realized by capacitive coupling of the third resonant column 700 with the first conducting band 400, so that the present technology can be integrated and applied to the port bandwidth adjustment of 5G frequency band (such as 3300MHz-3800MHz).

[0037] It should be noted that the "cavity 100" can be understood as a basic carrier such as a base, a mounting seat, a box body, etc., as long as it can meet the use requirements of the combiner.

[0042] The "first resonant column 300, the second resonant column 500, and the third resonant column 700" are any resonant column in the prior art that can meet the requirements.

Such an arrangement forms a double-layer chamber by using the first chamber 112 and the second chamber 114, which can reduce the interference of frequency band adjustment. Specifically, it is beneficial to reduce the interference on the frequency band 2 when adjusting the bandwidth of the frequency band 1 and the frequency band 3; or it is beneficial to reduce the interference on the frequency band 1 and the frequency band 3 when adjusting the bandwidth of the frequency band 2. At the same time, it can realize more and wider frequency bands of the combining and separating, and can be applied to the combiner to provide another option for the cavity arrangement of the combiner, which is beneficial to reduce the size of the combiner.
