Description

Technical Field

[0001] The invention relates to the field of antenna signal modulation, and in particular to a triple-frequency dual-polarization antenna. Background Art

[0002] In modern communication technology, antennas, as key components for signal transmission and reception, play a vital role. Especially in the fields of mobile communications, satellite communications, and the Internet of Things, the performance and flexibility of antennas directly affect the efficiency and reliability of the entire system. In recent years, with the increasing congestion of spectrum and the continuous development of technology, various types of multi-band antennas have emerged, becoming an important means to improve communication quality and spectrum utilization.

[0003] Triple-band dual-polarized antennas have gradually become a hot topic of research because they can work simultaneously on multiple frequency bands and receive and send signals in different polarization modes. This type of antenna can improve signal quality and reduce interference, and is widely used in wireless communication equipment, base stations, mobile terminals and other fields. However, the design of traditional triple-band dual-polarized antennas usually integrates all tuning units into a central control circuit board, which to a certain extent limits the maintainability and flexibility of the system and brings difficulties to the upgrade and repair of equipment.

[0004] Current technical solutions often lack modular thinking, resulting in the need to replace the entire circuit board if a tuning unit fails, which increases costs and maintenance complexity. Although this integrated design provides certain conveniences in saving space and initial design, it does not fully consider future maintenance and technology upgrade needs. With the continuous evolution of communication standards and technologies, users have put forward higher requirements for the performance improvement of antenna systems. Modular design is particularly important for quickly adapting to technological changes and simplifying maintenance processes.

[0005] Therefore, developing an innovative design that can distribute the different tuning units of the triple-band dual-polarized antenna on multiple modular circuit boards will effectively solve the limitations of the integrated design in the existing technology. Through this design, each tuning unit can be tested, maintained and replaced separately, which not only improves the flexibility of the equipment, but also greatly simplifies the maintenance process and reduces the management cost of users.

[0006] In addition, this modular design also allows for rapid adaptation to new frequency bands and technical requirements in future applications, with good scalability. Especially under the communication requirements of high frequency bands and complex scenarios, the performance of the antenna is crucial. Therefore, building a new type of triple-band dual-polarization antenna and configuring different tuning units on a modular circuit board is not only an effective way to respond to market demand, but also an important step in promoting the development of future communication equipment.

[0007] On the basis of the above, it is necessary to improve the assembly method of the three modular circuit boards and the central control circuit board to improve the efficiency of loading and removing the modular circuit boards, facilitate regular maintenance, and reduce equipment downtime and maintenance costs.

[0083] 1. Insert the modular circuit board 21 downward into the corresponding matching hole 22. This process will press down the lifting axis 62 until the upper expansion block 651 contacts the lifting axis 62 and stops under force. The third elastic member 79 is in a compressed state.

[0084] 2. The conductive pins 311 on the sub-conductive sockets 31 are respectively inserted into the main conductive sockets 32 to form an electrical connection between the corresponding modular circuit board 21 and the central control circuit board 11 .

[0085] 3. The two push-in blocks 52 will just correspond to the positions of the two side push-in surfaces 42. The two push-in blocks 52 will stably move outward under the elastic force applied by the first elastic member 56, and then extend into the side push-in surfaces 42 respectively, so as to achieve the purpose of limiting the sub-stop seat 40, and the modular circuit board 21 is firmly fixed in the corresponding matching hole 22.

[0086] When dismantling:

[0087] 1. Insert the outer tube led out from the energizing device into the air supply pipe 93. The air generated by the energizing device will enter the air inlet 78 through the air supply pipe 93. As the air continues to enter, it will automatically push the air lock main block 73 to continue to move left. Then, the air outlet 80 will be connected to the air inlet 78 to receive the air entering from the air inlet 78.

[0088] 2. The air then enters the air inlet cavity 57 through the first inner hole 82, the interconnected inner cavity 81, the second inner hole 83, the third inner hole 92 and the air inlet hole 58, and then enters the sealing area through the air inlet cavity 57. As the air continues to enter, the sealing area will continue to expand, thereby pushing the return block 53 and the resistance block 52 to move inward together.

[0089] 3. When the two abutting blocks 52 move inwards together and respectively leave the two side abutting surfaces 42, the restriction on the sub-stop seat 40 is released.

[0090] 4. Then, the lifting axis 62 will move upward, and then lift the modular circuit board 21 to disconnect the electrical connection with the central control circuit board 11, and at the same time move out the corresponding matching hole 22. The operator only needs to gently pull the modular circuit board 21 upward to complete the removal of the modular circuit board 21, which is labor-saving and convenient.

[0091] 5. In actual operation, it is only necessary to open the enabling device for a certain period of time and then close it. After no air enters, the third elastic member 79 will apply an elastic force to push the air locking main block 73 to move rightward. The lower end of the air locking main block 73 is in contact with the anti-slip gasket 77, and the right end is against the air inlet hole 78 and closes it, thereby preventing air leakage.

[0092] 6. After removing the modular circuit board 21, the switch element on the air exhaust pipe 95 is turned on to automatically exhaust the gas in the air bleed cavity 57.

[0093] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
