Description

Technical Field

[0001] This utility model relates to the field of wireless communication technology, and in particular to a vertically polarized omnidirectional antenna and module integrated device. Background Technology

[0002] In existing wireless communication devices, antennas are typically separate from radio frequency modules and control circuits, requiring connection via cables or connectors. This separate structure not only increases the overall size and weight of the device, hindering miniaturization and lightweight design, but also easily introduces additional signal loss and matching problems during connection, affecting the stability and transmission efficiency of the communication signal. Furthermore, improperly designed polarization of traditional antennas can also lead to increased signal loss during transmission, further reducing communication quality.

[0003] Therefore, there is an urgent need for an integrated component that can achieve miniaturization, lightweight design, low loss, and stable signal. Utility Model Content

[0004] The purpose of this invention is to address the problem that existing wireless communication devices are large in size and weight, which is not conducive to miniaturization and lightweight design, and to propose an integrated device for vertically polarized omnidirectional antennas and modules.

[0005] To achieve the above objectives, the present invention employs the following technology: a vertically polarized omnidirectional antenna and module integrated device, comprising an outer shell, a sealing cover detachably mounted on the top of the outer shell, and an integrally formed mounting plate at the bottom of the outer shell, wherein the internal space of the outer shell is divided into an antenna compartment and a module compartment by a positioning plate, wherein an antenna assembly is detachably mounted in the antenna compartment, and the module compartment is capable of assembling a radio frequency module and a circuit board.

[0006] As a further description of the above technical solution: the antenna assembly includes a ground plane and a metal radiating plate arranged in parallel, wherein the ground plane is connected to a positioning plate, and a feed post and a coupling post are provided between the ground plane and the metal radiating plate.

[0007] As a further description of the above technical solution: the number of coupling columns is several, and the several coupling columns are arranged at equal intervals around the axis of the power supply column between the floor and the metal radiant plate.

[0008] As a further description of the above technical solution: the diameter of the coupling column is larger than the diameter of the power supply column.

[0009] As a further description of the above technical solution: the bottom of the sealing cover extends downward to form a positioning frame integrally formed therewith, and a gasket that abuts against the edge of the metal radiation plate is provided inside the positioning frame.

[0010] As a further description of the above technical solution: the inner annular surface of the washer is trumpet-shaped.

[0011] As a further description of the above technical solution: the floor is detachably connected to the positioning plate via positioning screws;

[0012] The positioning plate has a guide post at the top corner, and a guide hole adapted to the guide post is opened on the floor.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] By integrating the antenna, RF module, and control circuitry into a single design, unnecessary space is reduced, resulting in miniaturization, weight reduction, and a smaller overall size, facilitating system integration. The antenna assembly employs a vertically polarized design, minimizing matching losses during signal transmission and improving communication signal stability. The overall device features small size, lightweight design, low power consumption, and high radiation performance, making it suitable for portable WLAN or UWB systems. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-5 This embodiment provides a vertically polarized omnidirectional antenna and module integrated device, including a housing 1, a sealing cover 2 detachably installed on the top of the housing 1, and a mounting plate 3 integrally formed therewith on the bottom of the housing 1.

[0024] In this invention, the outer shell 1 has a rectangular structure, with dimensions of 85mm in length, 52mm in width, and 21mm in height. The sealing cover 2 is detachably mounted on the outer shell 1 using screws. The mounting plate 3 has several symmetrically distributed mounting holes for easy fixing of the device to an external device using bolts.

[0025] The internal space of the outer casing 1 is divided into an antenna compartment 5 and a module compartment 6 by a positioning plate 4. The antenna compartment 5 is equipped with an antenna assembly 7 that can be detachably installed. The module compartment 6 can be equipped with an RF module and a circuit board. The antenna assembly 7 includes a floor 71 and a metal radiating plate 72 arranged in parallel. The floor 71 is connected to the positioning plate 4. A feed post 73 and a coupling post 74 are provided between the floor 71 and the metal radiating plate 72.

[0026] The antenna compartment 5 and module compartment 6 are separated by the positioning plate 4, placing the antenna assembly 7 in an independent space from the RF module and circuit board, thus avoiding mutual interference between different functional components during installation and operation. As the core component for signal radiation and reception, the physical separation of the antenna assembly 7 from the RF module and circuit board responsible for signal processing reduces the impact of electromagnetic interference generated by the module and circuit during operation on the antenna radiation performance, ensuring the stability of communication signals.

[0027] The antenna assembly 7 adopts a parallel arrangement of a ground plane 71 and a metal radiating plate 72, and together with the structure of a feed post 73 and a coupling post 74, it achieves vertical polarization omnidirectional radiation. The ground plane 71 serves as the basic structure of the antenna, providing a stable reference plane for radiation. The metal radiating plate 72 serves as the main radiating element. Under the excitation of the feed post 73 and the coupling effect of the coupling post 74, it can effectively radiate 2.4G band signals. Moreover, the vertical polarization characteristic reduces the matching loss during signal transmission, improving the stability and transmission efficiency of communication signals.

[0028] It should be noted that there are several coupling posts 74, and these coupling posts 74 are arranged at equal intervals around the axis of the feed post 73 between the ground plate 71 and the metal radiating plate 72. The diameter of the coupling posts 74 is larger than the diameter of the feed post 73. The equal intervals around the feed post 73 by the coupling posts 74 can form a symmetrical electromagnetic field distribution. Combined with the vertical polarization design, this can ensure that the antenna achieves uniform omnidirectional radiation in the horizontal direction, reduce the directional deviation of signal coverage, and improve the reception stability of 2.4G band signals in different directions. In addition, the larger diameter of the coupling posts 74 compared to the feed post 73 can enhance the electromagnetic coupling between them and the ground plate 71 and the metal radiating plate 72 through a larger metal surface area, thereby improving energy transfer efficiency.

[0029] Specifically, such as Figure 1 and Figure 4 As shown, the bottom of the sealing cover 2 extends downward to form a positioning frame 21 integrally formed therewith. A gasket 22 is provided inside the positioning frame 21 to abut against the edge of the metal radiation plate 72. The inner ring surface of the gasket 22 is trumpet-shaped.

[0030] After the antenna assembly 7 is installed inside the housing 1 via the positioning plate 4, the sealing cover 2 is then closed on the top of the housing 1. Since the size of the metal radiating plate 72 is smaller than that of the floor 71, in order to prevent the metal radiating plate 72 from shaking during use, the metal radiating plate 72 is pressed and fixed by the positioning frame 21 and the washer 22 when the sealing cover 2 is closed. Since the inner ring surface of the washer 22 is flared, it can ensure that the metal radiating plate 72 is accurately inserted into the positioning frame 21 when the sealing cover 2 is installed. The washer 22 can also greatly improve the stability of the antenna assembly 7.

[0031] Specifically, such as Figure 5 As shown, the floor 71 is detachably connected to the positioning plate 4 via positioning screws 41. A guide post 42 is provided at the top corner of the positioning plate 4, and a guide hole 711 adapted to the guide post 42 is provided on the floor 71. During antenna assembly 7 installation, the guide post 42 at the top corner of the positioning plate 4 is inserted into the corresponding guide hole 711 of the floor 71. The dimensional matching relationship between the two achieves pre-positioning, ensuring the accurate horizontal installation position of the floor 71 and preventing offset. After the guide post 42 completes pre-positioning, the floor 71 and the positioning plate 4 are locked together by the positioning screws 41, forming a rigid connection and ensuring structural stability after assembly.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
