Description

Technical Field

[0001] This utility model relates to the field of slot antenna technology, and in particular to a slot antenna. Background Technology

[0002] A slot antenna, also known as a slotted antenna, is an antenna formed by creating a slot in a conductor. It consists of a slot in a waveguide, metal plate, coaxial cable, or resonant cavity through which electromagnetic waves radiate into space. A typical slot shape is elongated, approximately half a wavelength (λ / 2) in length, and much narrower than a wavelength. The slot can be fed by a transmission line bridging its narrow side, or by a waveguide or resonant cavity. In this case, a radio frequency electromagnetic field is excited on the slot, radiating electromagnetic waves into space.

[0003] Conventional slot antenna mounting methods, such as direct welding, threaded connection, or bracket fixing, cannot flexibly adjust the mounting angle and make it inconvenient to optimize the antenna's directivity, thus affecting communication quality. Therefore, a slot antenna is proposed to solve the above problems. Utility Model Content

[0007] A connector is fixedly connected to the middle of the back of the metal plate, a main column is movably connected inside the connector, an end cap is fixedly connected to one end of the main column, and a bracket is fixedly connected to the other end of the main column.

[0008] The bottom end of the bracket is fixedly connected to a mounting base, the side of the bracket is fixedly connected to a spring, the end of the spring is fixedly connected to a first clamp, the first clamp and the spring are sleeved on the surface of the main column, the side of the connector is fixedly connected to a second clamp, and the first clamp and the second clamp have multi-toothed surfaces that fit together.

[0009] Preferably, in any of the above embodiments, the metal plate is rectangular in shape, and the tilt angle of the metal plate is adjustable.

[0010] Using the above technical solution, this slot antenna can be fed in various ways, including transmission line feeding across the narrow side of the slot, waveguide feeding, and resonant cavity feeding.

[0011] The working principle of a slot antenna is based on the radiation and reception of electromagnetic waves. When a radio frequency electromagnetic field is excited on the slot, it radiates electromagnetic waves into space. These electromagnetic waves radiate into the external space through the slot, thus forming a type of aperture antenna.

[0012] Preferably, in any of the above embodiments, the gaps are arranged in a linear array on the metal plate, and the inner side of the end abuts against the outer side of the connector.

[0013] The above technical solution utilizes conventional slot antenna mounting methods, such as direct welding, threaded connections, or bracket fixation. This provides slot antennas with significant flexibility and convenience in practical applications.

[0014] This device is an improvement based on the bracket fixation.

[0015] Preferably, in any of the above embodiments, the bracket is welded to the main column, and the bottom end of the bracket is welded to the mounting base.

[0016] The core structure of this device, employing the above technical solution, consists of: a connector, main column, end cap, bracket, mounting base, spring, first locking head, and second locking head. The core advantages of this device are: it improves upon the bracket-type fixing of slot antennas. A connector is installed on the back of the antenna's main metal plate, allowing free rotation on the main column and enabling free adjustment of the overall antenna angle. Before adjustment, the first locking head is pulled away, compressing the spring. After adjustment, the spring is released, and the first locking head is pushed back. The teeth of the first locking head engage with the teeth of the second locking head of the rotated connector, locking the connector after angle adjustment. This allows for quick positioning of the slot antenna after angle adjustment, enabling rapid and convenient angle adjustment. Traditional slot antenna angle adjustment requires tools or complex operations, while this device, through its freely rotating connector and spring locking mechanism, makes angle adjustment simple and quick, greatly improving work efficiency.

[0017] Users can adjust the antenna angle at any time to adapt to different communication environments and requirements. This flexibility allows the device to perform excellently in a variety of application scenarios. By precisely adjusting the antenna angle, users can optimize the antenna's directivity, thereby improving communication quality. This advantage is particularly evident in complex or constrained communication environments.

[0018] Preferably, in any of the above solutions, the mounting base has pre-drilled holes at its four corners, and the spring is of high strength.

[0019] Preferably, in any of the above solutions, an outer ring is fixedly connected to the outer surface of the first clamping head, and the second clamping head will still be adapted to the tooth surface of the first clamping head after rotation.

[0020] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0021] This slotted antenna, through the coordinated arrangement of a connector, main post, end cap, bracket, mounting base, spring, first locking head, and second locking head, is an improvement upon the bracket-type fixation of slotted antennas. A connector is installed on the back of the antenna's main metal plate, allowing free rotation on the main post to achieve free adjustment of the overall antenna angle. Before adjustment, the first locking head is pulled away, compressing the spring. After adjustment, the spring is released, and the first locking head is pushed back. The teeth of the first locking head engage with the teeth of the second locking head of the rotated connector, thus locking the connector after angle adjustment. This allows for quick positioning of the slotted antenna after angle adjustment, enabling fast and convenient angle adjustment and greater flexibility. Traditional slotted antenna angle adjustment requires tools or complex operations, while this device, with its freely rotating connector and spring locking mechanism, makes angle adjustment simple and quick, greatly improving work efficiency.

[0022] Users can adjust the antenna angle at any time to adapt to different communication environments and requirements. This flexibility allows the device to perform excellently in a variety of application scenarios. By precisely adjusting the antenna angle, users can optimize the antenna's directivity, thereby improving communication quality. This advantage is particularly evident in complex or constrained communication environments.

This slot antenna can be fed in various ways, including transmission line feeding across the narrow side of the slot 2, waveguide feeding, and resonant cavity feeding. The slots 2 are linearly arrayed on the metal plate 1, with the inner side of the end 5 abutting the outer side of the connector 3. Conventional slot antenna mounting methods include direct welding, threaded connection, or fixing with a bracket.

[0040] The overall angle of the antenna is freely adjustable. Before adjustment, pull away the first locking head 9 to compress the spring 8. After adjustment, release the spring 8 and push the first locking head 9. The teeth of the first locking head 9 engage with the teeth of the second locking head 10 of the rotated connector 3, thereby locking the connector 3 after angle adjustment. This allows for quick positioning of the slot antenna after angle adjustment.

[0041] Compared with the prior art, the present invention has the following advantages:

The teeth of the first locking head 9 engage with the teeth of the second locking head 10 of the rotated connector 3, thus locking the connector 3 after angle adjustment. This allows for quick positioning of the slot antenna after angle adjustment, enabling fast and convenient angle adjustment and greater flexibility. Traditional slot antenna angle adjustment requires tools or complex operations, while this device, through the freely rotating connector 3 and the locking mechanism of the spring 8, makes angle adjustment simple and quick, greatly improving work efficiency.
