Description

Technical Field

[0001] This utility model relates to the field of antenna technology, and in particular to a single-polarization dual-frequency high-gain wall-mounted antenna. Background Technology

[0002] Wall-mounted antennas are a major component of indoor distributed antennas, used in wireless communication systems such as WLAN and LTE. They are primarily used for indoor signal coverage, such as in parking lots, hotels, conference halls, guesthouses, office buildings, and other places requiring indoor distributed system coverage. To avoid impacting the indoor environment, the requirements for indoor distributed antennas are becoming increasingly stringent: they must be environmentally friendly, smaller in size, support more frequency bands, have more regular radiation directionality, and higher gain.

[0003] In existing technologies, traditional single-polarized wall-mounted antennas, in order to support dual frequencies, typically use a combination of a low-frequency radiating element and a high-frequency radiating element, linked together by a combiner. This combined structure is large in size, heavy in weight, complex in manufacturing, and has high production costs. Furthermore, the combiner has energy losses, making it difficult to achieve the expected radiation efficiency and gain. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a single-polarization dual-frequency high-gain wall-mounted antenna to overcome the shortcomings of the prior art.

[0005] This utility model provides a single-polarization dual-frequency high-gain wall-mounted antenna, comprising:

[0006] Housing assembly;

[0007] A radiation assembly is disposed within the housing assembly. The radiation assembly includes two metal dipoles, a metal feed plate, a metal parasitic coupling plate, a polygonal annular metal parasitic coupling plate, and two bi-shaped metal parasitic coupling plates.

[0008] The two metal dipoles are symmetrically arranged at the bottom of the housing assembly. The metal feed plate is fixed between the two metal dipoles and is connected to the two metal dipoles by non-contact coupling. The metal parasitic coupling piece is fixed above the metal feed plate and is disposed inside the polygonal annular metal parasitic coupling piece. The polygonal annular metal parasitic coupling piece is fixed above the metal dipoles. The two strip-shaped metal parasitic coupling pieces are symmetrically fixed above the polygonal annular metal parasitic coupling piece.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: the radiation assembly composed of two metal dipoles, a metal feed plate, a small metal parasitic coupling plate, a polygonal ring metal parasitic coupling plate, and two shaped metal parasitic coupling plates effectively reduces the size and weight of the antenna, thereby reducing the cost of production and processing. The metal feed plate set between the two metal dipoles can effectively improve the impedance bandwidth at low frequencies. The small metal parasitic coupling plate and the polygonal ring metal parasitic coupling plate can improve impedance matching and radiation directivity. Furthermore, the two shaped metal parasitic coupling plates can increase the convergence of the radiation pattern and effectively improve the gain.

[0011] Furthermore, a groove is provided on one side wall of the lower metal shell, and a hole is provided at the bottom of the upper plastic shell, with the hole corresponding to the groove.

[0013] Furthermore, the top of the metal feed plate is arranged so that one end gradually increases in size towards the other end.

[0014] Furthermore, the metal dipole is a metal sheet, and the metal dipole is configured with a stepped structure.

[0026] Please see Figures 1 to 2 The image shows a single-polarization dual-frequency high-gain wall-mounted antenna in an embodiment of this utility model, including a housing assembly 10 and a radiating assembly 20.

[0027] The radiation component 20 is disposed within the housing assembly 10. The housing assembly 10 includes a lower metal shell 11 and an upper plastic shell 12. The upper plastic shell 12 covers the lower metal shell 11, and the lower metal shell 11 has a U-shaped structure. The radiation component 20 is disposed inside the lower metal shell 11 and the upper plastic shell 12. The radiation component 20 includes two metal dipoles 21, a metal feed plate 22, a small metal parasitic coupling plate 23, a polygonal annular metal parasitic coupling plate 24, and two linear metal parasitic coupling plates 25. The two metal dipoles 21 are symmetrically arranged within the housing assembly 10. At the bottom, the metal feed plate 22 is fixed between the two metal dipoles 21 and is connected to the two metal dipoles 21 by non-contact coupling. The metal parasitic coupling piece 23 is fixed above the metal feed plate 22 and is disposed inside the polygonal annular metal parasitic coupling piece 24. The metal parasitic coupling piece 23 and the polygonal annular metal parasitic coupling piece 24 are on the same plane. The polygonal annular metal parasitic coupling piece 24 is fixed above the metal dipoles 21. The two strip-shaped metal parasitic coupling pieces 25 are symmetrically fixed above the polygonal annular metal parasitic coupling piece 24.

[0028] It should be explained that the two metal dipoles 21 are symmetrically arranged on the upper surface of the metal lower shell 11. In this embodiment, the metal lower shell 11, the two metal dipoles 21, the metal feed plate 22, the metal parasitic coupling plate 23, the polygonal annular metal parasitic coupling plate 24, and the two triangular metal parasitic coupling plates 25 are all made of sheet metal, which facilitates processing and effectively reduces production costs. Furthermore, the radiating component 20 enables the antenna to operate in the frequency bands of 698MHz-960MHz and 1710MHz-2700MHz.

[0029] It is worth noting that the metal dipole 21 is a metal sheet, and the metal dipole 21 is configured with a stepped structure. In this embodiment, the metal dipole 21 acts as a radiating oscillator.

[0030] Furthermore, in this embodiment, the strip-shaped metal parasitic coupling piece 25 is similar to a rectangular arrangement, and the two strip-shaped metal parasitic coupling pieces 25 can increase the convergence of the radiation pattern and effectively improve the antenna gain.

[0031] Specifically, in this embodiment, a groove 110 is provided on one side wall of the lower metal shell 11, and a hole 120 is provided at the bottom of the upper plastic shell 12, with the hole 120 corresponding to the groove 110. One end of a coaxial antenna 210 is connected to one side wall of a metal dipole 21, and the other end of the coaxial antenna 210 penetrates the side wall of the housing assembly 10.

[0032] It should be noted that one end of the coaxial antenna 210 extends to the outside of the metal lower shell 11 and the plastic upper shell 12 through the groove 110 on the metal lower shell 11 and the hole 120 on the plastic upper shell 12.

[0033] Specifically, in this embodiment, the top end of the metal feed plate 22 is set from small to large towards the other end. It should be explained that the metal feed plate 22 adopts a gradual design from small to large, which effectively improves the impedance bandwidth of high and low frequencies.

[0034] Specifically, in this embodiment, the metal parasitic coupling patch 23 has a rectangular structure, and the polygonal annular metal parasitic coupling patch 24 has a closed structure. It should be noted that the metal parasitic coupling patch 23 can also be a polygonal structure. The metal parasitic coupling patch 23 and the polygonal annular metal parasitic coupling patch 24 can effectively improve impedance matching and radiation directionality.

[0035] In summary, the single-polarization dual-band high-gain wall-mounted antenna in the above embodiments of this utility model effectively reduces the size and weight of the antenna by using a radiation assembly composed of two metal dipoles 21, a metal feed plate 22, a metal parasitic coupling piece 23, a polygonal ring metal parasitic coupling piece 24, and two shaped metal parasitic coupling pieces 25. This reduces production and processing costs. The metal feed plate 22, located between the two metal dipoles 21, effectively improves the impedance bandwidth at low frequencies. The metal parasitic coupling piece 23 and the polygonal ring metal parasitic coupling piece 24 improve impedance matching and radiation directivity. Furthermore, the two shaped metal parasitic coupling pieces 25 increase the convergence of the radiation pattern, effectively improving the gain.
