Technical Field

[0001] The utility model relates to the technical field of slot antennas, in particular to a slot antenna. Background Art

[0002] Slot antenna, also known as slot antenna, is an antenna formed by opening a slot on a conductor surface. This antenna is formed by opening a slot on a metal plate, waveguide, coaxial line or resonant cavity, so that electromagnetic waves can radiate to the outer space through these slots, thus forming an aperture antenna. The slot shape of the slot antenna is usually long and strip-shaped, with a length of about half a wavelength, and a radio frequency electromagnetic field is excited on the slot, which can radiate electromagnetic waves into space.

The slot antenna and the electronic device equipped with the slot antenna are arranged on different surfaces of a metal shell, which can solve the problem of the large size of the slot antenna and reduce the space requirement of this type of antenna. However, the slot antenna and the electronic device equipped with the slot antenna have exposed slots, which are easily interfered with and affect the signal effect. Utility Model Content

[0007] The above technical solution is adopted: by setting a support net made of polyester fiber material above the main body of the dielectric antenna to support and protect the top of the slot, it is possible to prevent the dielectric antenna main body from contacting surrounding equipment or materials and causing corrosion damage. The polyester fiber will not affect the signal of the dielectric antenna, making the dielectric antenna more anti-interference and suitable for situations with more complex installation environments.

[0015] The utility model has the following advantages:

[0016] 1. The slot antenna provides a support net made of polyester fiber above the main body of the dielectric antenna to support and protect the top of the slot, thereby preventing the dielectric antenna main body from contacting surrounding equipment or materials and causing corrosion damage. The polyester fiber will not affect the signal of the dielectric antenna, making the dielectric antenna more resistant to interference and suitable for situations where the installation environment is relatively complex. The air inside the support net can still circulate, and will not affect the heat dissipation efficiency of the slot dielectric antenna. A rotating protective plate is provided above the wiring terminal, and when the dielectric antenna is wired, the protective plate can be rotated open for wiring. After the wiring is completed, the protective plate automatically closes under the torsion of the torsion spring to protect the wiring terminal that has completed the wiring, thereby reducing external interference on the wiring terminal and reducing the probability of poor contact of the dielectric antenna.

The distance between the support net 4 and the top of the dielectric antenna body 1 is less than two millimeters. By arranging the support net 4 made of polyester fiber above the dielectric antenna body 1, the top of the slot 2 is supported and protected, which can prevent the dielectric antenna body 1 from contacting with surrounding equipment or materials and causing corrosion damage. The polyester fiber will not affect the signal of the dielectric antenna, so that the dielectric antenna has a stronger anti-interference ability and is suitable for situations where the installation environment is more complex. The air inside the support net 4 can still circulate, and will not affect the heat dissipation efficiency of the slot dielectric antenna.

[0029] Embodiment 2: A protective plate 7 is rotatably connected to one side of the top of the dielectric antenna body 1 . The protective plate 7 is located above the wiring terminal 3 . When the protective plate 7 is horizontal, the wiring terminal 3 is completely covered.

[0030] Embodiment 3: A torsion spring 8 is sleeved on the middle part of the rotating shaft of the protective plate 7. The torsion of the torsion spring 8 makes the protective plate 7 parallel to the top surface of the dielectric antenna body 1. By arranging a rotatable protective plate 7 above the wiring terminal 3, when the dielectric antenna is wired, the protective plate 7 can be rotated open for wiring. After the wiring is completed, the protective plate 7 automatically closes under the torsion of the torsion spring 8 to protect the wiring terminal 3 that has completed the wiring, thereby reducing external interference on the wiring terminal and reducing the probability of poor contact of the dielectric antenna.

By arranging a shrinkable mounting plate 6 at the bottom of the dielectric antenna body 1, when the mounting plate 6 is not needed for fixation, the mounting plate 6 is retracted in the shrinkage groove 5 to avoid the mounting plate 6 occupying extra space. When the mounting plate 6 is needed to assist in fixing the antenna, the mounting plate 6 is partially slid out of the shrinkage groove 5 and screwed into the mounting plate 6, so that the dielectric antenna is fixedly connected to the mounting surface, thereby improving the stability of the dielectric antenna.

[0035] S2. A rotatable protective plate 7 is provided above the wiring terminal 3. When the dielectric antenna is being wired, the protective plate 7 can be rotated open for wiring. After the wiring is completed, the protective plate 7 is automatically closed under the torsion of the torsion spring 8 to protect the wiring terminal 3 that has completed the wiring, thereby reducing external interference on the wiring terminal and reducing the probability of poor contact of the dielectric antenna.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

The slot antenna provides a support net 4 made of polyester fiber above the dielectric antenna body 1 to support and protect the top of the slot 2, thereby preventing the dielectric antenna body 1 from contacting surrounding equipment or materials and causing corrosion damage. The polyester fiber will not affect the signal of the dielectric antenna, making the dielectric antenna more resistant to interference and suitable for situations where the installation environment is relatively complex. The air inside the support net 4 can still circulate, and will not affect the heat dissipation efficiency of the slot dielectric antenna. A rotating protective plate 7 is provided above the wiring terminal 3, and when the dielectric antenna is connected, the protective plate 7 can be rotated open for wiring. After the wiring is completed, the protective plate 7 is automatically closed under the torsion of the torsion spring 8, and the wiring terminal 3 that has been connected is protected, thereby reducing external interference on the wiring terminal and reducing the probability of poor contact of the dielectric antenna.
