Description

Technical Field

[0001] This utility model relates to the field of horn antenna technology, specifically a 1-18 GHz four-ridged dual-polarized horn antenna. Background Technology

[0002] Horn antennas are directional radiating antennas widely used in the microwave and millimeter-wave bands. They consist of a rectangular or circular waveguide port that gradually expands into a horn-shaped structure. The core of the antenna achieves efficient radiation and reception of microwave signals through the gradual transition at the horn opening, featuring high gain, strong directivity, and a wide bandwidth. They are widely used in radar detection, satellite communication, electronic measurement, and other fields. Their operating bandwidth, polarization flexibility, ease of assembly and disassembly, and structural stability directly affect signal transmission efficiency and system adaptability, making them a key component in microwave systems.

[0003] Existing horn antennas have many obvious shortcomings. On the one hand, their operating bandwidth is limited, and most products cannot cover the ultra-wide frequency range of 1-18GHz. Different specifications of antennas need to be replaced when facing different frequency application scenarios, resulting in poor adaptability and high usage costs. On the other hand, polarization mode switching is inconvenient, and it is impossible to flexibly achieve rapid conversion between dual polarization and single polarization. Complex modifications or replacement of the entire component are required, which is cumbersome and affects work efficiency. Utility Model Content

[0029] Example 1

[0030] Combination Figures 1 to 7 A 1-18 GHz quad-ridged dual-polarized horn antenna includes a mounting bracket 3, a mounting mechanism 1 on the left side of the mounting bracket 3, a rear cavity 41 inside the mounting mechanism 1, a horn antenna body 4 fixedly connected to the front side of the rear cavity 41, a ridge plate 5 inside the horn antenna body 4, and a disassembly mechanism 2 on the outside of the horn antenna body 4.

[0031] The mounting mechanism 1 includes a support assembly 11, a mounting assembly 12, and a locking assembly 13. The support assembly 11 is located on the left side of the mounting frame 3, the mounting assembly 12 is located inside the support assembly 11, and the locking assembly 13 is located on the left and right sides of the mounting assembly 12.

[0032] Support assembly 11 includes an L-shaped bracket 1101, which is located on the left side of mounting bracket 3. A retaining strip 1102 is snapped into the right side of the L-shaped bracket 1101 and fixedly connected to the left side of mounting bracket 3. A bolt 1103 is located on the rear side of retaining strip 1102 and snaps into the L-shaped bracket 1101. The bolt 1103 is threaded into mounting bracket 3. Mounting assembly 12 includes a sleeve frame 1201, which is fixedly connected to the front side of L-shaped bracket 1101 and fits onto the outer ring of rear cavity 41. Sliders 1202 are slidably connected to the left and right sides of sleeve frame 1201. A limit frame 1203 is slidably connected to the outer side of slider 1202. A limit slider 1204 is fixedly connected to the inner side of limit frame 1203 and fixedly connected to sleeve frame 1201. On the left and right sides, the limiting slider 1204 is slidably connected to the slide 1202. The top of the slide 1202 is fixedly connected to the card plate 1205. The card plate 1205 passes downward through the sleeve frame 1201 and is engaged in the top of the rear cavity 41. The locking assembly 13 includes a fixing box 1301. The fixing box 1301 is fixedly connected to the left and right sides of the slide 1202. A sliding piece 1302 is slidably connected inside the fixing box 1301. A compression spring 1303 is fixedly connected to the outside of the sliding piece 1302. A locking rod 1304 is fixedly connected to the inside of the sliding piece 1302. The locking rod 1304 passes through the slide 1202 and is engaged in the sleeve frame 1201. A telescopic sliding rod 1305 is fixedly connected to the outside of the sliding piece 1302. The telescopic sliding rod 1305 is slidably connected to the inside of the outside of the fixing box 1301. A pull rod 1306 is fixedly connected to the outside of the telescopic sliding rod 1305.

[0033] Furthermore, the mounting bracket 3 and the rear cavity 41 are connected by an L-shaped bracket 1101. As needed, the staff can disassemble and assemble the rear cavity 41 or the rear cavity 41 and the L-shaped bracket 1101 as a whole. At the same time, the staff only needs to rotate the bolt 1103 or pull the pull rods 1306 on both sides to disassemble the L-shaped bracket 1101 or the rear cavity 41, which is convenient for the staff to disassemble and assemble the horn antenna body 4. The operation is simple and easy for the staff to use.

[0034] Example 2

[0035] See Figure 1 , Figure 2 , Figure 4 and Figure 8 Furthermore, based on Embodiment 1, the disassembly mechanism 2 includes a mounting component 21 and a fixing component 22. The mounting component 21 is disposed inside the horn antenna body 4, and the fixing component 22 is disposed outside the horn antenna body 4.

[0036] The mounting assembly 21 includes a mounting slide rail 2101, which is fixedly connected to the inner side of the horn antenna body 4 and slidably connected to the inner side of the ridge plate 5. A limiting slide rail 2102 is fixedly connected to the inner side of the mounting slide rail 2101 and is snapped into the ridge plate 5. The fixing assembly 22 includes a threaded drum 2201, which is rotatably connected to the inner side of the horn antenna body 4 corresponding to the position of the ridge plate 5. A threaded rod 2202 is threadedly connected to the inner ring of the threaded drum 2201. The threaded rod 2202 passes through the horn antenna body 4 and is snapped into the inner side of the ridge plate 5. A limiting guide rod 2203 is slidably connected to the inner side of the threaded rod 2202. A fixing bracket 2204 is fixedly connected to the outer side of the limiting guide rod 2203. The fixing bracket 2204 is sleeved on the outer side of the threaded drum 2201 and is fixedly connected to the outer side of the horn antenna body 4.

[0037] Furthermore, the limiting slide rail 2102 cooperates with the threaded rod 2202 to lock the position of the ridge plate 5 set inside the horn antenna body 4. At the same time, the operator only needs to rotate the threaded drum 2201 to control the threaded rod 2202 to disengage from the ridge plate 5, so that the operator can directly move the ridge plate 5 forward to complete the disassembly of the ridge plate 5. This makes it convenient for the operator to disassemble and assemble the ridge plate 5, so that the antenna horn can be switched between bipolar and monopolar as needed, and it is also convenient for the operator to replace different models of ridge plates 5.

[0038] In actual operation, when this device is in use and the rear cavity 41 needs to be disassembled, the staff first pulls the pull rods 1306 on both sides outward. The pull rods 1306 move outward, which drives the locking rod 1304 outward through the telescopic slide rod 1305 and the sliding plate 1302. The locking rod 1304 moves outward and retracts into the fixed box 1301. Then the staff moves the slide 1202 upward. The slide 1202 moves upward, which drives the locking plate 1205 upward to disengage from the rear cavity 41 and the frame 1201. After that, the staff can move the horn antenna body 4 forward to complete the disassembly of the horn antenna body 4.

[0039] When it is necessary to disassemble the L-shaped bracket 1101, the staff only needs to rotate the bolt 1103 to disassemble it, and then move the L-shaped bracket 1101 to the left.

[0040] When it is necessary to disassemble the spine plate 5, the worker first rotates the threaded drum 2201. The rotation of the threaded drum 2201 controls the threaded rod 2202 to move outward. The outward movement of the threaded rod 2202 disengages it from the spine plate 5. Then, the worker moves the spine plate 5 forward. The spine plate 5 moves forward and disengages from the connection between the mounting slide rail 2101 and the limiting slide rail 2102. At this point, the disassembly of the spine plate 5 is completed.

[0041] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
