Description
Technical Field
[0001] The utility model belongs to the technical field of mobile communication equipment, and in particular relates to a single-band antenna. Background Art
[0002] With the rapid development of wireless communication technology, antennas are an indispensable part of wireless communication systems, and their performance directly affects the quality and efficiency of the entire communication system. Nowadays, the technical requirements for antennas are increasing, especially in a single frequency band. The realization of efficient and stable communication has become the focus of research.
[0003] At present, the design of single-band antennas mainly uses the radiation boundary to converge the antenna beam. The radiation boundary is generally higher in height to achieve a better convergence effect. However, as a complete plate-like structure, the higher the height of the radiation boundary, the more materials are consumed and the higher the economic cost. Utility Model Content
[0004] The technical purpose of the utility model is to provide a single-band antenna, aiming to reduce the production cost.
[0005] In order to solve the above technical problems, the utility model is implemented as follows: a single-band antenna, comprising:
[0006] A reflector, a plurality of radiation units and a plurality of radiation sheets;
[0007] The reflector includes a plate body and a first radiation boundary, wherein the first radiation boundary extends along the length direction of the plate body and extends toward a first direction along two side edges of the plate body;
[0008] The plurality of radiation units are installed on one side of the plate body facing the first direction and are arranged at intervals along the length direction of the plate body. The plurality of radiation sheets correspond to the plurality of radiation units one by one and are installed at one end of the first radiation boundary away from the plate body.
[0009] The acute angle between the first direction and the thickness direction of the plate body ranges from 0° to 45°.
[0010] In one embodiment, along the thickness direction of the plate body, the height of the first radiation boundary is 20 mm to 40 mm, and the height of the radiation sheet is 20 mm to 30 mm; along the length direction of the plate body, the length of the radiation sheet is 30 mm to 40 mm.
[0011] In one of the embodiments, a plurality of mounting openings are provided on the first radiation boundary, the number of the mounting openings is greater than the number of the radiation sheets, and the radiation sheets are detachably connected to the first radiation boundary through the mounting openings.
[0012] In one of the embodiments, a second radiation boundary is further included. A plurality of radiation units are divided into two columns and installed on the plate. The second radiation boundary is located between the two columns of radiation units and extends along the length direction of the plate. The second radiation boundary is installed on the plate and extends toward the first direction.
[0013] In one embodiment, the second radiation boundary includes two intermediate radiation boundary plates facing two columns of radiation units on both sides, and the two intermediate radiation boundary plates are inclined toward each other.
[0014] In one embodiment, the acute angle between the two intermediate radiation boundary plates and the plate body is 60° to 80°.
[0015] In one embodiment, a cross section of the second radiation boundary along its length direction is a trapezoid.
[0016] In one embodiment, the length of the upper base of the trapezoid is 8 mm to 12 mm, and the length of the lower base of the trapezoid is 50 mm to 60 mm.
[0017] In one embodiment, the reflector further includes a third radiation boundary, which extends along the length direction of the plate body and extends toward a second direction along two sides of the plate body; wherein the second direction deviates from the first direction based on the thickness direction of the plate body.
[0018] In one embodiment, along the thickness direction of the plate body, the height of the third radiation boundary is 20 mm to 40 mm.
[0019] Compared with the prior art, the single-band antenna in the utility model has the following beneficial effects: in the present application, since the radiation units are arranged at intervals, some areas of the first radiation boundary do not interact with the radiation units to produce effects, so the height of the first radiation boundary can be set lower, and the radiation plates arranged at the same intervals are used to replace the vacant first radiation boundary to achieve the effect of adjusting the beam width and the cross-plan ratio. Therefore, the total area of the first radiation boundary plus the radiation plate becomes smaller, and the sum of the costs of the two is also lower than the manufacturing cost of the first radiation boundary in the past, and the effect is the same as before.

[0026] Refer to Figure 1 , Figure 1 which shows a schematic structural diagram of a single-band antenna. In one embodiment, the present application provides a new single-band antenna, the main structure of which includes a reflector, a plurality of radiation units 200 and a plurality of radiation patches 300. The reflector includes a plate body 100 and a first radiation boundary 110. The first radiation boundary 110 extends along the length direction of the plate body 100 and extends outwards towards the first direction along both sides of the plate body 100. A plurality of radiation units 200 are all installed on one side of the plate body 100 facing the first direction and are arranged at intervals along the length direction of the plate body 100. A plurality of radiation patches 300 correspond to the plurality of radiation units 200 one by one and are installed at one end of the first radiation boundary 110 facing away from the plate body 100. The included acute angle range between the first direction and the thickness direction of the plate body 100 is from 0° to 45°.
[0027] In the above embodiments, since the radiation units 200 are arranged at intervals, there are some regions of the first radiation boundary 110 that do not interact with the radiation units 200 to produce effects. Therefore, the height of the first radiation boundary 110 can be set lower, and instead, the radiation sheets 300 arranged at the same intervals are used to replace the missing first radiation boundary 110 to perform functions, achieving the adjustment of beam width and other index effects such as cross-plan ratio. Therefore, the total area of the first radiation boundary 110 plus the radiation sheets 300 becomes smaller, so the sum of the costs of the two is also lower than the manufacturing cost of the first radiation boundary 110 in the past.
[0028] Preferably, the first direction is perpendicular to the thickness direction of the plate body 100, and at the same time, corresponding angular changes are made according to the specific parameters of the radiation unit 200. The range of the acute angle between the first direction and the thickness direction of the plate body 100 is 0° to 45°, that is, the range of the angle between the first direction and the plate body 100 is between 45° and 135°.
[0029] Preferably, in one embodiment, along the thickness direction of the plate body 100, the height of the first radiation boundary 110 is 20 mm to 40 mm, and the height of the radiation sheet 300 is 20 mm to 30 mm; along the length direction of the plate body 100, the length of the radiation sheet 300 is 30 mm to 40 mm. The specific values can be set according to the specific indicators of the single-band antenna.
[0030] Preferably, in one embodiment, a plurality of mounting openings are provided on the first radiation boundary 110, the number of the mounting openings is more than the number of the radiation sheets 300, and the radiation sheets 300 are detachably connected to the first radiation boundary 110 through the mounting openings. The number and spacing distance of the radiation units 200 will change according to different requirements. The radiation sheets 300 can be adaptively matched with the positions of the radiation units 200 by being detachably connected to the first radiation boundary 110, thereby improving the applicability. The detachable connection method can be in forms such as bolt connection, snap connection, riveting, etc. When the requirements are fixed, fixed connection methods such as welding can also be used.
[0031] In one embodiment, Figure 1 Two columns of radiation units 200 are provided, and each column of radiation units 200 is arranged along the length direction of the plate body 100 by a plurality of radiation units 200. Therefore, a second radiation boundary 120 is added between the two columns of radiation units 200. The plurality of radiation units 200 are divided into two columns and installed on the plate body 100. The second radiation boundary 120 is located between the two columns of radiation units 200 and extends along the length direction of the plate body 100. The second radiation boundary 120 is installed on the plate body 100 and protrudes in the first direction. The functions of the second radiation boundary 120, the first radiation boundary 110, and the radiation sheets 300 are the same.
[0032] Preferably, referring to Figure 2 , Figure 2 , a cross-sectional schematic diagram of a single-band antenna is provided. In one embodiment, the second radiation boundary 120 includes two intermediate radiation boundary plates facing two columns of radiation units 200 on both sides, and both intermediate radiation boundary plates are inclined towards each other. As can be seen from Figure 2 , the cross-section of the second radiation boundary 120 is an isosceles triangle, and the two intermediate radiation boundary plates intersect.
[0033] Preferably, in one embodiment, the acute angle between the two intermediate radiation boundary plates and the plate body 100 is 60° to 80°. That is, the angle range of the two base angles of the triangle of the second radiation boundary 120 in Figure 2 is 60° to 80°.
[0034] In the above embodiment, the inclination angles of the two intermediate radiation boundary plates are the same. It can be understood that in other embodiments, according to different index parameters, the inclination angles of the two intermediate radiation boundary plates can be different.
[0035] In one embodiment, the cross-section of the second radiation boundary 120 along its length direction is a trapezoid, preferably an isosceles trapezoid. That is, the straight lines where the two intermediate radiation boundary plates are located will intersect, but they do not intersect, but form the two waists of the isosceles trapezoid. The function of the second radiation boundary 120 with a trapezoidal cross-section is to adjust the beam width of the broadband antenna. By the gradient-changing side boundary spacing, the beam width of a part of the frequency band is adjusted with less influence on other frequency bands.
[0036] Preferably, in one embodiment, the upper base length of the trapezoid is 8 mm to 12 mm, and the lower base length of the trapezoid is 50 mm to 60 mm. The specific values can be determined according to relevant parameter indicators.
[0037] Referring to Figure 1 , in one embodiment, the reflector further includes a third radiation boundary 130, and the third radiation boundary 130 extends along the length direction of the plate body 100 and extends out towards the second direction along the two side edges of the plate body 100. Referring to Figure 1 Or Figure 2 , taking the thickness direction of the plate body 100 as a reference, the second direction is away from the first direction.
[0038] In one embodiment, along the thickness direction of the plate body 100, the height of the third radiation boundary 130 is 20 mm to 40 mm. The specific values can be determined according to relevant parameter indicators.
[0039] In the above embodiment, the first radiation boundary 110 and the plate body 100 are of an integral structure. The two side edges of the plate body 100 are bent, and the bent parts form the first radiation boundary 110. When the size of the radiation unit 200 is relatively long, the bending length, that is, the height of the first radiation boundary 110, can be increased to enhance the structural strength. Both the radiation sheet 300 and the third radiation boundary 130 are sheet metal parts.
[0040] The foregoing are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
