Description

Technical Field

[0001] The utility model belongs to the technical field of wireless communication, and particularly relates to a direct-clamping type microwave duplexer and a direct-clamping type microwave antenna. Background Technique

[0002] Microwave communication refers to communication using microwave signals with frequencies ranging from 300 MHz to 3000 GHz, and a microwave antenna is a key component for microwave communication.

[0003] With the development of microwave communication, single-band microwave communication can no longer meet the market needs. Various forms of dual-band or multi-band microwave communication have emerged in the market. Among them, a dual-band microwave antenna generally means that the E-band and the conventional band share a reflector, and a multi-band microwave antenna means that the high-frequency band and the low-frequency band in the conventional band share a reflector. However, whether it is a dual-band microwave antenna or a multi-band microwave antenna, the difference between the two bands is at least doubled. In actual applications, there are some requirements that hope two adjacent frequency bands share a reflector to achieve the effect of multi-band communication, such as W6G and W7G, 13G and 15G, 18G and 23G, and so on.

[0004] In addition, microwave antennas not only have a split application scenario, that is, using a rectangular flexible waveguide to connect the microwave antenna and an external ODU device; there is also a direct-clamping application scenario where the external ODU device is directly connected to the antenna. And multi-band antennas with adjacent frequency bands also have a direct-clamping application requirement.

[0005] Patent CN219086234U discloses a direct-clamping type multi-band microwave parabolic antenna, which can not only achieve adjacent frequency bands but also belongs to a direct-clamping application. However, both ports of the duplexer in this patent are arranged on the same end face. During actual use, in order to prevent interference between the duplexer and the central disk or the hanging rack, it is usually necessary to re-customize the central disk, making the size of the central disk larger than that of a conventional central disk, that is, it is necessary to re-customize the microwave broadband antenna to effectively prevent interference.

The duplexer core 2 is connected to an external ODU device through the low-frequency port connector 4 and the high-frequency port connector 3, and is connected to the microwave broadband antenna through the common port connector 5.

[0044] Specifically, the high-frequency port 21, the low-frequency port 22, and the common port 23 are all rectangular waveguides, and the rectangular waveguides of the high-frequency port 21 and the low-frequency port 22 are equal in size and the same in polarization direction as the rectangular waveguide of the common port 23.

The connection line between the intersection of the diagonals of the square formed by the four threaded holes 111 on the first side of the frame 11 and the intersection of the diagonals of the square formed by the four threaded holes 111 on the second side coincides with the center lines of the high-frequency port connector 3 and the low-frequency port connector 4.

[0046] Further, in some embodiments, the common port connector 5 includes a first cylinder and a second cylinder that are concentrically arranged, and the diameter of the second cylinder is smaller than that of the first cylinder; the first cylinder is snap-fitted into the through hole 121, and the second cylinder protrudes from the side of the through hole 121 facing away from the receiving cavity 10. By snap-fitting the first cylinder into the through hole 121, the duplexer core 2 connected with the high-frequency port connector 3, the low-frequency port connector 4, and the common port connector 5 can be stably assembled in the receiving cavity 10.

[0047] Further, in some embodiments, a straight snap-on microwave antenna includes a main reflector, a rectangular outlet broadband feed disposed on one side of the main reflector, a central disk connected to the side of the main reflector facing away from the rectangular outlet broadband feed, and a straight snap-on microwave duplexer as described above. The common port 23 is docked with the rectangular outlet broadband feed, and the first mounting structure is assembled and connected to the central disk.

[0048] Specifically, the main reflector, the rectangular outlet broadband feed, and the central disk are connected and combined to form a microwave broadband antenna. Through the straight snap-on microwave duplexer, the dual-frequency communication function of two adjacent frequency bands of the microwave broadband antenna can be realized, and the straight snap-on application can be achieved. Among them, the common port 23 is docked with the rectangular outlet broadband feed through the common port connector 5, the high-frequency port 21 is docked with an external ODU device through the high-frequency port connector 3, and the low-frequency port 22 is docked with the external ODU device through the low-frequency port connector 4; the first mounting structure of the mounting frame 1 is assembled and connected to the central disk to realize the straight snap-on connection between the straight snap-on microwave duplexer and the microwave broadband antenna, and the second mounting structure is used for assembling and connecting with an external ODU device to realize the straight snap-on connection between the straight snap-on microwave antenna and the ODU device. Since the first surface and the second surface of the duplexer core 2 are oppositely arranged, that is, the high-frequency port 21 and the low-frequency port 22 are oppositely arranged on two surfaces of the duplexer core 2, when connecting the straight snap-on microwave duplexer and the microwave broadband antenna, there will be no interference, and there is no need to customize a broadband microwave antenna to achieve the dual-frequency function. A conventional broadband microwave antenna can be used, which reduces the cost.

[0049] It should be noted that the frequency band of the straight snap-on microwave duplexer is consistent with that of the microwave broadband antenna. Exemplarily, the frequency bands of the microwave broadband antenna can be 5.925 - 7.125G, 7.125 - 8.5G, 10 - 11.7G, 12.75 - 13.25G, 14.4 - 15.35G, etc. Additionally, the mounting bracket 1 in the straight snap-on microwave duplexer can be shared. That is, the frequency band of the straight snap-on microwave duplexer depends on the different designs of the duplexer core 2, and the size of the rectangular waveguide at each port of the duplexer core 2 is related to the frequency. The larger the size of the rectangular waveguide, the lower the frequency; the smaller the size, the higher the frequency. Therefore, by changing the size of the rectangular waveguide at each port of the duplexer core 2, the frequency band of the straight snap-on microwave duplexer can be changed to adapt to the frequency band of the microwave broadband antenna.

In summary, the content of this specification should not be construed as a limitation to the present utility model.
