Description

Technical Field

[0001] This utility model relates to a microwave antenna, and more particularly to a sleeve-type directional microwave antenna. Background Technology

[0002] In the field of radio communication technology, microwave signals are widely used due to their high frequency, fast transmission speed, strong penetration, and good directionality. For example, in various scenarios such as vehicle management at level crossings and personnel management, microwave signals can track and locate target objects in real time and accurately, and can also maintain stable signal transmission in complex environments, providing strong technical support for managers.

[0003] However, traditional microwave receiving antennas lack directional constraints when receiving signals, making it impossible to accurately determine the direction of the signal source. When multiple radio microwave signals in the same frequency band (≥2.4GHz and above) are transmitted simultaneously in the effective area, the receiving antenna often collects all the signals in the area at once, making it difficult to determine the location of the signal source.

[0004] Traditional microwave receiving antennas typically employ antenna array technology to address this issue. However, antenna arrays not only require complex hardware configurations and are costly, but they are also susceptible to interference from the surrounding environment, such as multipath effects and signal reflections, which can affect the accuracy and stability of signal reception. Utility Model Content

[0005] In view of the above-mentioned shortcomings of current microwave receiving antennas, this utility model provides a sleeve-type directional microwave antenna. The sleeve structure effectively constrains and adjusts the microwave signal receiving angle, thereby improving the accuracy of signal source direction determination. By adjusting the connecting rod, the position of the antenna assembly within the sleeve body can be changed, thereby adjusting the microwave signal receiving angle and range to meet the needs of different scenarios.

[0006] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions:

[0008] The antenna assembly is fitted with a sleeve with an opening at one end, and the end of the antenna assembly with the antenna faces the opening of the sleeve.

[0009] The antenna assembly is connected to a connecting rod at one end away from the opening of the sleeve. The connecting rod passes through the bottom of the sleeve to adjust the distance between the antenna assembly connected to it and the opening of the sleeve.

[0010] The inner side of the sleeve is covered with a microwave-absorbing coating.

[0011] According to one aspect of this utility model, the antenna is a PCB directional antenna.

[0027] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] like Figure 1 and Figure 2 As shown, a sleeve-type directional microwave antenna includes an antenna assembly 2, a sleeve 1, and a connecting rod 3.

[0030] The antenna assembly 2 has an antenna 21 at one end to receive microwave signals, and a circuit board 22 is provided inside the antenna assembly 2 to process the microwave signals received by the antenna 21. Specifically, the antenna 21 can be a PCB directional antenna, etc.

[0031] The antenna assembly 2 is externally fitted with a sleeve 1, one end of which has an opening. The end of the antenna assembly 2 with the antenna faces the opening of the sleeve 1. The opening of the sleeve 1 facilitates the antenna's reception of microwave signals, and the angle at which the microwave signal is received is controlled by the distance between the antenna and the opening of the sleeve 1. The closer the antenna is to the opening of the sleeve 1, the wider the angle, and the greater the angle at which the antenna can receive microwave signals; conversely, the farther the antenna is from the opening of the sleeve 1, the smaller the angle, and the smaller the angle at which the antenna can receive microwave signals.

[0032] The antenna assembly 2 is connected to a connecting rod 3 at one end opposite to the opening of the sleeve 1. The connecting rod 3 passes through the bottom of the sleeve 1 to adjust the distance between the antenna assembly 2 and the opening of the sleeve 1. Specifically, the position of the antenna assembly can be adjusted by pulling the connecting rod outward and pushing it inward. When the connecting rod is pulled outward, it moves the antenna assembly towards the bottom of the sleeve, away from the opening of the sleeve; when the connecting rod is pushed inward, it moves the antenna assembly towards the opening of the sleeve, away from the bottom of the sleeve.

[0033] The inner side of the sleeve 1 is covered with a microwave absorbing coating to prevent microwave signals from penetrating the surface of the sleeve and reaching the antenna. It also prevents microwave signals from being reflected back to the antenna after reaching the inner wall of the sleeve through the sleeve opening. This ensures that all microwave signals can only reach the antenna directly through the sleeve opening. Specifically, the microwave absorbing coating can be made of magnetic materials, conductive polymers, or carbon-based materials, etc.

[0034] In practical applications, the sleeve-type directional microwave antenna in this embodiment can be used to adjust the position of the antenna assembly within the sleeve via a connecting rod, thereby adjusting the signal receiving angle of the microwave antenna. For example... Figure 3 As shown, when the antenna assembly is closer to the sleeve opening, the signal reception sector is larger, and the microwave antenna can receive signals from more angles, resulting in a wider range of signal sources. When the antenna assembly is farther away from the sleeve opening, the signal reception sector is smaller, and the microwave antenna can receive signals from smaller angles and more consistent directions, resulting in a more precise signal source.

[0035] This device can effectively prevent signals from the sides and rear of the antenna from shining onto the antenna by moving the antenna position back and forth inside a sleeve that microwaves cannot penetrate or reflect, thereby accurately determining the direction of the signal source.

[0036] The beneficial effects of this embodiment are as follows: The sleeve-type directional microwave antenna provided in this embodiment, based on the characteristics of short microwave wavelength and poor diffraction performance, effectively constrains and adjusts the microwave signal receiving angle through the sleeve structure, thereby improving the accuracy of signal source direction determination; by adjusting the connecting rod, the position of the antenna assembly within the sleeve body can be changed, thereby adjusting the microwave signal receiving angle and range to meet the needs of different scenarios; the microwave absorbing coating on the inner side of the sleeve can reduce the influence of environmental interference, and compared with common antenna array direction determination schemes, it is lower in cost.

[0037] Example 2

[0038] like Figure 1 and Figure 2 As shown, a sleeve-type directional microwave antenna includes an antenna assembly 2, a sleeve 1, and a connecting rod 3.

[0039] The antenna assembly 2 has an antenna 21 at one end to receive microwave signals, and a circuit board 22 is provided inside the antenna assembly 2 to process the microwave signals received by the antenna 21. Specifically, the antenna 21 can be a PCB directional antenna, etc.

[0040] The antenna assembly 2 is externally fitted with a sleeve 1, one end of which has an opening. The end of the antenna assembly 2 with the antenna faces the opening of the sleeve 1. The opening of the sleeve 1 facilitates the antenna's reception of microwave signals, and the angle at which the microwave signal is received is controlled by the distance between the antenna and the opening of the sleeve 1. The closer the antenna is to the opening of the sleeve 1, the wider the angle, and the greater the angle at which the antenna can receive microwave signals; conversely, the farther the antenna is from the opening of the sleeve 1, the smaller the angle, and the smaller the angle at which the antenna can receive microwave signals.

[0041] The antenna assembly 2 is connected to a connecting rod 3 at one end opposite to the opening of the sleeve 1. The connecting rod 3 passes through the bottom of the sleeve to adjust the distance between the connected antenna assembly and the sleeve opening. Specifically, the position of the antenna assembly can be adjusted by pulling the connecting rod outward or pushing it inward. When the connecting rod is pulled outward, it moves the antenna assembly towards the bottom of the sleeve, away from the sleeve opening; when the connecting rod is pushed inward, it moves the antenna assembly towards the sleeve opening, away from the bottom of the sleeve.

[0042] The inner side of the sleeve 1 is covered with a microwave absorbing coating to prevent microwave signals from penetrating the surface of the sleeve and reaching the antenna. It also prevents microwave signals from being reflected back to the antenna after reaching the inner wall of the sleeve through the sleeve opening. This ensures that all microwave signals can only reach the antenna directly through the sleeve opening. Specifically, the microwave absorbing coating can be made of magnetic materials, conductive polymers, or carbon-based materials, etc.

[0043] To facilitate actual installation and use, a wire hole 13 can be provided on the side wall of the sleeve for leading out the power and data cables of the antenna assembly; a fixing bracket 14 can also be provided on the side wall of the sleeve for installing and fixing the sleeve.

[0044] The sleeve can be designed as a cuboid, right prism, or cylinder. Different shapes correspond to different antenna signal reception angles, and the shape of the sleeve can be designed according to actual needs and specific application scenarios. The vertical cross-sectional shape of the antenna assembly is the same as that of the sleeve, making it easy for the two to fit together.

[0045] In practical applications, the sleeve-type directional microwave antenna in this embodiment can be used to adjust the position of the antenna assembly within the sleeve via a connecting rod, thereby adjusting the signal receiving angle of the microwave antenna. For example... Figure 3As shown, when the antenna assembly is closer to the sleeve opening, the signal reception sector is larger, and the microwave antenna can receive signals from more angles, resulting in a wider range of signal sources. When the antenna assembly is farther away from the sleeve opening, the signal reception sector is smaller, and the microwave antenna can receive signals from smaller angles and more consistent directions, resulting in a more precise signal source.

[0046] This device can effectively prevent signals from the sides and rear of the antenna from shining onto the antenna by moving the antenna position back and forth inside a sleeve that microwaves cannot penetrate or reflect, thereby accurately determining the direction of the signal source.

[0047] The beneficial effects of this embodiment are as follows: The sleeve-type directional microwave antenna provided in this embodiment also has a wire hole and a fixing bracket on the side wall of the sleeve, which facilitates practical use.

[0051] The antenna assembly 2 is externally fitted with a sleeve 1, one end of which has an opening. The end of the antenna assembly 2 with the antenna faces the opening of the sleeve 1.

[0052] The antenna assembly 2 is connected to a connecting rod 3 at one end opposite to the opening of the sleeve 1. The connecting rod 3 passes through the bottom of the sleeve to adjust the distance between the connected antenna assembly and the sleeve opening. Specifically, the position of the antenna assembly can be adjusted by pulling the connecting rod outward or pushing it inward. When the connecting rod is pulled outward, it moves the antenna assembly towards the bottom of the sleeve, away from the sleeve opening; when the connecting rod is pushed inward, it moves the antenna assembly towards the sleeve opening, away from the bottom of the sleeve.

[0053] The inner side of the sleeve 1 is covered with a microwave absorbing coating to prevent microwave signals from penetrating the surface of the sleeve and reaching the antenna. It also prevents microwave signals from being reflected back to the antenna after reaching the inner wall of the sleeve through the sleeve opening. This ensures that all microwave signals can only reach the antenna directly through the sleeve opening.

The vertical cross-sectional shape of the antenna assembly is the same as that of the sleeve, making it easy for the two to fit together.

[0056] In addition, the sleeve can also be configured as a detachable type, including a tube body 11 with openings at both ends and a rear cover 12 detachably mounted on one end of the tube body. When it is necessary to maintain or repair components such as antennas and circuit boards inside the sleeve, the rear cover of the sleeve can be easily removed without the need for complex disassembly of the entire antenna system, thus simplifying the maintenance and repair process.

[0057] In practical applications, the sleeve-type directional microwave antenna in this embodiment can be used to adjust the position of the antenna assembly within the sleeve via a connecting rod, thereby adjusting the signal receiving angle of the microwave antenna. For example... Figure 3 As shown, when the antenna assembly is closer to the sleeve opening, the signal reception sector is larger, and the microwave antenna can receive signals from more angles, resulting in a wider range of signal sources.

[0059] The beneficial effects of this embodiment are as follows: the sleeve-type directional microwave antenna provided in this embodiment is also designed to be detachable, which facilitates the maintenance or repair of the antenna, circuit board and other components inside the sleeve.
