Description

Technical Field

[0001] This application relates to the field of flat panel antennas, and more specifically, to a dual-sided low-frequency flat panel antenna. Background Technology

[0002] For low-frequency flat panel antennas, the industry standard for front-to-back ratio is greater than or equal to 16dB. Low frequencies are typically found in the 824MHz-960MHz band and are commonly used in 4G networks. However, with advancements in technology, in many cases, to improve network quality, a front-to-back ratio of greater than or equal to 20dB is required, and sometimes even greater than or equal to 25dB. A typical flat panel antenna structure consists of a base plate and two sides.

[0003] A planar antenna refers to an antenna that propagates in only one specific direction;

[0004] In existing installation methods, antennas are mounted on signal towers using clamps. While clamps simplify installation, they expose the antenna to the elements, which can cause the clamps to loosen and affect the antenna's initial position.

[0005] Currently, there is no dual-sided low-frequency flat panel antenna that is easy to install and stable. Summary of the Invention

[0063] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0064] A dual-sided 102 low-frequency flat panel antenna includes: a flat panel antenna body 100 and a mounting device 1;

[0065] The flat panel antenna body 100 includes an antenna base plate 101 and side edges 102. The side edges 102 are located on both sides of the antenna base plate 101 and are fixedly connected to the antenna base plate 101. There are two side edges 102 on each side of the antenna base plate 101. The antenna base plate 101 is equipped with a mounting device 1 for mounting the antenna body on an outdoor utility pole.

[0066] The mounting device 1 includes: a mounting ring 2, a slide groove 211, a slider 221, and a clamping assembly 3;

[0067] The mounting ring 2 is formed by joining two semicircular rings end to end. The two semicircular rings constituting the mounting ring 2 are defined as the first semicircular ring 21 and the second semicircular ring 22. The end of the first semicircular ring 21 is provided with a groove 211, which extends along the circumferential direction of the first semicircular ring 21. The end of the second semicircular ring 22 is formed with a slider 221 that is inserted into the groove 211. The slider 221 can slide along the extension trajectory of the groove 211. The slider 221 is also provided with a clamping component 3 for fixing the mounting ring 2 to the utility pole. More specifically, both the slider 221 and the groove 211 are arc-shaped, and the arc surface is concentric with the arc of the first semicircular ring 21 or the second semicircular ring 22. In this way, the first semicircular ring 21 and the second semicircular ring 22 can adapt to utility poles with different shaft diameters, improving the adaptability of the installation.

[0068] A movable groove 212 is formed within the first semicircular ring 21. The movable groove 212 is arc-shaped and concentrically arranged with the first semicircular ring 21. A movable plate 23 is movably disposed within the movable groove 212 and can move along the radial direction of the first semicircular ring 21. The movable plate 23 is located on the surface of the movable groove 212 away from the central axis of the first semicircular ring 21. More specifically, the end portion of the first semicircular ring 21 opposite to the end with the sliding groove 211 is recessed to form a mating groove 24. The second semicircular ring 22 is provided with an abutting block 25 corresponding to the mating groove 24. The bottom wall of the mating groove 24 is provided with a pressing plate 26. A connecting rod 28 is fixed on the surface of the pressing plate and extends into the movable groove 212. The pressing plate 26 is connected to the mating groove 24 by a spring 27, which always provides the pressing plate 26 with an elastic force away from the surface of the mating groove 24.

[0069] More specifically, the surface of the movable plate 23 away from the positioning pin 4 has an inclined groove 231; the portion of the connecting rod 28 located in the movable groove 212 has a push rod that inserts into the inclined groove 231; wherein, the inclined groove 231 is inclined away from the central axis of the first semicircular ring 21, so that the push rod slides in the inclined groove 231, causing the movable plate 23 to move; when the abutting block 25 is inserted into the mating groove 24, it will abut against the pressing plate 26, thereby driving the pressing plate 26 to move, and driving the connecting rod 28 to move; since the push rod is inserted into the inclined groove 231, as the connecting rod 28 moves, the push rod will slide along the trajectory of the inclined groove 231, thereby pushing the movable plate 23 to move in the axial direction of the first semicircular ring 21;

[0070] More specifically, a positioning pin 4 is rotatably mounted on the movable plate 23. The end of the positioning pin 4 away from the movable plate 23 is conical and is used to insert into the surface of the utility pole. The inner wall of the movable groove 212 extends through the axis of the mounting ring 2 to form a movable hole 41. A spiral groove 411 is formed on the inner wall of the movable hole 41, and the positioning pin 4 is partially embedded in the spiral groove 411. As the movable plate 23 moves, it will drive the positioning pin 4 to move towards the axis of the first semi-circular ring 21. At the same time, the part of the positioning pin 4 embedded in the spiral groove 411 will cause the positioning pin 4 to rotate while moving. This arrangement makes it easier for the positioning pin 4 to be embedded into the utility pole. Because of the positioning pin 4, after the mounting ring 2 is installed, it provides a limit to the axial direction of the utility pole, improving the stability of the mounting ring 2 installation.

[0071] The clamping assembly 3 includes: a limiting rod 31, a limiting tooth 32, and a locking tooth 33;

[0072] A limiting rod 31 is disposed at the end of the slider 221, with one end extending into the moving groove 212. A plurality of limiting teeth 32 are evenly distributed on the limiting rod 31 located within the moving groove 212. A retaining tooth 33 is provided on the moving plate 23 to abut against the limiting teeth 32. Both the limiting teeth 32 and the retaining tooth 33 have mutually abutting inclined surfaces. When the limiting teeth 32 and the retaining tooth 33 abut against each other, the inclined surfaces cause the limiting rod 31 to move, further clamping the mounting ring 2. For example, during installation, to make the first semicircular ring 21 and the second semicircular ring... 22 is more adaptable to the shaft diameter of the utility pole, driving the slider 221 to rotate clockwise within the slide groove 211; when the first semicircular ring 21 and the second semicircular ring 22 have been installed, the contact between the limiting tooth 32 and the locking tooth 33 can drive the slider 221 to rotate counterclockwise within the slide groove 211 a certain distance, thus further clamping the utility pole; since the distance that the limiting tooth 32 and the locking tooth 33 can drive the slider 221 to move is always consistent, the clamping is fixed each time, so there will be no phenomenon of damage to the mounting ring 2 due to excessive clamping force.

[0073] The ends of the first semicircular ring 21 and the second semicircular ring 22 are each provided with mounting pieces 5; each mounting piece 5 has a mating hole; a bolt 6 is provided in the mating hole; after the first semicircular ring 21 and the second semicircular ring 22 are fitted onto the outer wall of the utility pole, the two mounting pieces 5 are brought closer together by simply turning the bolt 6; when turning, the slider 221 will automatically slide to adapt to the shaft diameter of the utility pole; when the two mounting pieces 5 are pressed together, the abutment block drives the pressure plate 26 to move completely; at this point, the limiting tooth 32 and the locking tooth 33 abut together to clamp the first semicircular ring 21 and the second semicircular ring 22 onto the utility pole; therefore, simply turning the bolt 6 to drive the two mounting pieces 5 to press together can realize the movement of the positioning nail 4 and the clamping of the mounting ring 2, improving the convenience of installation.

[0074] A guide rail 7 is formed on the outer wall of the mounting ring 2, extending around the circumference of the mounting ring 2. A slide rod 71 is slidably mounted inside the guide rail 7, with the arc circumference of the slide rod 71 being 1 / 3 of the circumference of the mounting ring 2. A mounting plate 72 is fixedly mounted on the surface of the slide rod 71, which is used to mount the flat panel antenna body 100. After the mounting ring 2 is installed, the slide rod 71 can be slidable to adjust the flat panel antenna body 100, making it easier to adjust its position. Since the arc circumference of the slide rod 71 is 1 / 3 of the circumference of the mounting ring 2, it can fill the gap between the guide rail 7 and the first and second mounting rings when the guide rail 7 slides, thus making the adjustment of the angle position more stable and convenient. An internal threaded hole is formed through the surface of the slide rod 71, and a screw is installed in the internal threaded hole. The end of the screw abuts against the outer wall of the mounting ring 2. When the flat panel antenna is adjusted to the appropriate position, the screw is turned to drive the end of the screw to abut against the outer wall of the mounting ring 2, thereby achieving fixation.
