Description

Technical Field

[0001] The utility model relates to the technical field of antennas, in particular to an omnidirectional high-gain horizontally polarized antenna. Background Art

[0002] The I-shaped antenna consists of a feed board and two identical antenna boards. Multiple clamping parts are provided at both ends of the feed board, and corresponding clamping slots are provided on the two antenna boards. The two antenna boards are assembled on the feed board by clamping the clamping parts with the clamping slots. However, the assembly of the components is not stable enough with only the clamping assembly method. It is necessary to set copper sheets on the edges of certain clamping slots for welding and fixing but without electrical connection to the antenna structure, and to weld at the position where the antenna board and the feed board are clamped to strengthen the antenna structure. However, in the actual welding process, it was found that it was difficult to control the antenna board to be perpendicular to the feed board, and welding was difficult. In terms of performance, the copper sheets set on the antenna board to reinforce the structure and the solder joints formed by welding have a coupling effect on the antenna board, resulting in a deterioration in the roundness of the antenna pattern.

[0033] See also Figure 8The I-shaped antenna consists of a feed board and two identical antenna boards. Multiple clamping parts are provided at both ends of the feed board, and corresponding clamping slots are provided on the two antenna boards. The two antenna boards are assembled on the feed board by clamping the clamping parts with the clamping slots. However, the assembly of the components is not stable enough relying solely on the clamping assembly method. It is necessary to set copper sheets on the edges of certain clamping slots for welding and fixing but without electrical connection to the antenna structure, and to weld at the position where the antenna board and the feed board are clamped to strengthen the antenna structure. However, in the actual welding process, it was found that it was difficult to control the antenna board to be perpendicular to the feed board, and welding was difficult. In terms of performance, the copper sheets set on the antenna board to reinforce the structure and the solder joints formed by welding have a coupling effect on the antenna board, resulting in a deterioration in the roundness of the antenna pattern.

[0034] Reference Figures 1 to 7 In view of this, the utility model proposes an omnidirectional high-gain horizontal polarization antenna, comprising: a first dielectric plate 1 and a second dielectric plate 2. The first dielectric plate 1 is provided with a feeding structure 3 and a first slot 11, and the second dielectric plate 2 is provided with a radiator 21 and a second slot 22. The first dielectric plate 1 and the second dielectric plate 2 are plugged into each other through the first slot 11 and the second slot 22. The feeding structure 3 is electrically connected to the radiator 21. The feeding structure 3 can be a microstrip line or a coaxial cable.

[0035] The technical solution of the utility model optimizes the clamping structure of the feed board in the I-shaped antenna and the clamping slot structure on the antenna board by adopting a method that the first dielectric plate 1 is provided with a first slot 11 and the second dielectric plate 2 is provided with a second slot 22, and the first dielectric plate 1 and the second dielectric plate 2 are plugged into each other through the first slot 11 and the second slot 22. With the arrangement of the above scheme, the first dielectric plate 1, that is, the feed board is no longer provided with a clamping portion but becomes a first slot 11; the second dielectric plate 2, that is, the antenna board is changed from the original multiple slots to a single second slot 22. The first dielectric plate 1 and the second dielectric plate 2 are plugged into each other through the first slot 11 and the second slot 22, which is conducive to maintaining the vertical position relationship between the second dielectric plate 2 and the first dielectric plate 1, reducing the number of slots, optimizing the copper sheet structure, and at the same time reducing the number of solder joints 4 reserved at the clamping position for reinforcing the first dielectric plate 1 and the second dielectric plate 2, reducing the difficulty of welding, improving the stability of the assembly of the first dielectric plate 1 and the second dielectric plate 2, and facilitating installation. At the same time, the first dielectric plate 1 and the second dielectric plate 2 are perpendicular to each other after being plugged into each other, so as to facilitate subsequent welding and reinforcement.

[0036] See also Figure 7 ,in Figure 7This is a comparison diagram of the average gain of the utility model on the 5.8G main beam plane (phi = 90°). Due to the optimization of the copper sheet structure and the reduction of the number of solder joints 4, the coupling between the copper sheet and some solder joints 4 and the antenna is reduced, and the circularity of the antenna pattern of the utility model omnidirectional high-gain horizontal polarization antenna is improved compared with the circularity of the original antenna pattern.

[0037] See also Figure 3 and Figure 4 In one embodiment, the radiator 21 is an Alfort ring, two of which are arranged on both sides of the second dielectric plate 2 .

[0038] See also Figures 1 to 4 In one embodiment, the two Alford rings are arranged on both sides of the second dielectric plate 2 in a symmetrical manner about the center of the second dielectric plate 2. In this embodiment, the two Alford rings are respectively connected to the conductor in the feeding structure 3 and the ground to construct a uniform ring current. Compared with the I-shaped antenna balun feeding method, the ring current amplitude of the utility model fluctuates less.

[0039] See also Figure 1 , Figure 2 and Figure 7 In one embodiment, the second dielectric plate 2 is set to be multiple, the first slot 11 is correspondingly set to be multiple, the multiple first slots 11 are arranged at intervals on the first dielectric plate 1, and the multiple second dielectric plates 2 are plugged into the multiple first slots 11 one by one. In this embodiment, compared with the two-unit module antenna of the original I-shaped antenna, the omnidirectional high-gain horizontally polarized antenna of the utility model is a multi-unit module antenna. Specifically, the utility model is a 4-unit module antenna, which has an average gain improvement of 2.5dB on the 5.8G main beam plane (phi=90°) compared with the original two-unit module antenna. Of course, the utility model is not limited to this. In some embodiments, it can also be an antenna with more unit modules, such as a 6-unit module antenna, an 8-unit module antenna, etc., and it only needs to set the number of the second dielectric plates 2 to 6 or 8.

[0040] See also Figure 1 , Figure 2 , Figure 5 and Figure 6 In one embodiment, the feeding structure 3 is a power divider 31 , and the power divider 31 has a plurality of feeding branches 311 , and each of the radiators 21 is electrically connected to a feeding branch 311 .

[0041] See also Figure 1 , Figure 2In order to reinforce the first dielectric plate 1 and the second dielectric plate 2, in one embodiment, the second dielectric plate 2 is welded to the first dielectric plate 1. In this embodiment, specifically, one side edge of the first slot 11 is welded to one side edge of the second slot 22. The feeding branch 311 is arranged on the first dielectric plate 1 and is located at one side edge of the first slot 11. Through such an arrangement, the feeding branch 311 is staggered from the second dielectric plate 2 so as to reserve enough space for the second dielectric plate 2 to be welded to the first dielectric plate 1.

[0042] Preferably, the welding position of one side edge of the first slot 11 and one side edge of the second slot 22 is located on the feeding branch 311. In this embodiment, the radiator 21 is electrically connected to the feeding structure 3 through the welding point 4 formed by welding the second dielectric plate 2 and the first dielectric plate 1.

[0043] See also Figure 5 and Figure 6 In this embodiment, the power divider 31 is disposed on the first side surface of the first dielectric plate 1 and the second side surface away from the first surface. The two power dividers 31 are mirror-imaged on both sides of the first dielectric plate 1, and the feeding branches 311 opposite to each other on the two power dividers 31 form a parallel double-line structure. The structural design of the parallel double-line structure is essentially a balun, which naturally provides a phase difference of 180° and is conducive to the miniaturization of the structure. In this embodiment, the power divider 31 is composed of a microstrip line and can be disposed on the first dielectric plate 1 by printing.

[0044] The present application also provides a communication device, which includes the above-mentioned omnidirectional high-gain horizontally polarized antenna.

[0045] The technical solution of the utility model optimizes the clamping structure of the feed board in the I-shaped antenna and the clamping slot structure on the antenna board by adopting a method that the first dielectric plate 1 is provided with a first slot 11 and the second dielectric plate 2 is provided with a second slot 22, and the first dielectric plate 1 and the second dielectric plate 2 are plugged into each other through the first slot 11 and the second slot 22. With the arrangement of the above scheme, the first dielectric plate 1, that is, the feed board is no longer provided with a clamping portion but becomes a first slot 11; the second dielectric plate 2, that is, the antenna board is changed from the original multiple slots to a single second slot 22. The first dielectric plate 1 and the second dielectric plate 2 are plugged into each other through the first slot 11 and the second slot 22, which reduces the number of slots and optimizes the copper sheet structure. At the same time, it also reduces the number of solder joints 4 reserved at the clamping position for strengthening the first dielectric plate 1 and the second dielectric plate 2, improves the stability of the assembly of the first dielectric plate 1 and the second dielectric plate 2, reduces the difficulty of welding, and facilitates installation. At the same time, the first dielectric plate 1 and the second dielectric plate 2 are perpendicular to each other after being plugged into each other, which facilitates subsequent welding for reinforcement. A plurality of first slots 11 may be provided on the first dielectric plate 1 so as to plug in a plurality of the second dielectric plates 2 to obtain a multi-unit module antenna, which is beneficial to improving gain compared with a two-unit module antenna of an I-shaped antenna.
