Description

Technical Field

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

[0002] Dielectric antenna is a type of antenna that uses dielectric materials as radiating elements. Its working principle is mainly based on the electromagnetic properties of dielectric materials. Through specific shape and structural design, the antenna can effectively radiate and receive electromagnetic waves at specific frequencies. Dielectric antennas are usually composed of dielectric resonators, dielectric rods or other dielectric structures. These dielectric structures can have different shapes and sizes to meet different application requirements.

[0003] A small ceramic dielectric antenna with a shielding cover RFID UHF is disclosed in Chinese patent CN201420368544.9. The small ceramic dielectric antenna with a shielding cover RFID UHF is assembled together with a shielding cover of an RFID UHF reader circuit module by connecting an isolation plate. The small ceramic dielectric antenna with a shielding cover RFID UHF has good reliability, stability and operability. However, the small ceramic dielectric antenna with a shielding cover RFID UHF uses a shielding cover to wrap the dielectric antenna as a whole, and no heat dissipation structure is provided, which affects the overall heat dissipation efficiency of the dielectric antenna and has poor durability when used in a high temperature environment. Utility Model Content

[0006] Optionally, the inner shape of the protective corner sleeve is matched with the four-corner shape of the dielectric antenna body, the material of the protective corner sleeve is ceramic, and the corners of the protective corner sleeve are rounded.

[0007] The above technical solution is adopted: by arranging a ceramic base and a protective corner sleeve made of ceramic material on the outside of the dielectric antenna body, the dielectric antenna is fully protected, the durability of the dielectric antenna is improved, and storage and installation are convenient. The protective corner sleeve can reserve a part of space on the top of the dielectric antenna after installation, which is convenient for air circulation and heat dissipation.

The wavy heat sink has a larger contact area with the air and can dissipate heat faster.

[0010] Optionally, circular grooves are formed at four corners of the bottom of the ceramic base, and suction cups are fixedly connected inside the circular grooves.

[0011] By adopting the above technical solution, a suction cup is arranged at the bottom of the ceramic base, so that the dielectric antenna can be initially fixed by the suction cup when installing the dielectric antenna, which is convenient for positioning and installation.

[0012] Optionally, the bottom of the support sheet opens outwards, the support sheet is made of alloy spring steel, and the bottom height of the support sheet is equal to the bottom height of the ceramic base when the inner side of the support sheet is in contact with the protective corner sleeve.

[0016] The utility model has the following advantages:

[0017] 1. The ceramic dielectric antenna provides full protection for the dielectric antenna by arranging a ceramic base and a protective corner sleeve made of ceramic material on the outside of the dielectric antenna body, thereby improving the durability of the dielectric antenna and facilitating storage, installation and use. The protective corner sleeve can reserve a portion of space on the top of the dielectric antenna after installation, which is convenient for air circulation and heat dissipation. Ceramics also have good thermal conductivity, thereby improving the heat dissipation efficiency of the dielectric antenna. By arranging a plurality of wavy heat sinks on both sides of the dielectric antenna body, the heat conduction efficiency inside the dielectric antenna can be accelerated, and the dielectric antenna can quickly dissipate heat in a high temperature environment, thereby improving the durability of the dielectric antenna. The wavy heat sink has a larger contact surface with the air and can dissipate heat faster.

[0029] Embodiment 1: The inner shape of the protective corner sleeve 3 is adapted to the four corners of the dielectric antenna body 1. The material of the protective corner sleeve 3 is ceramic, and the corners of the protective corner sleeve 3 are rounded. By arranging a ceramic base 2 and a protective corner sleeve 3 made of ceramic material on the outside of the dielectric antenna body 1, the dielectric antenna is fully protected, the durability of the dielectric antenna is improved, and storage and installation are convenient. The protective corner sleeve 3 can reserve a part of the space on the top of the dielectric antenna after installation, which is convenient for air circulation and heat dissipation. Ceramics also have good thermal conductivity, thereby improving the heat dissipation efficiency of the dielectric antenna.

[0030] Embodiment 2: The heat sinks 4 are all wavy in shape, and the inner sides of the heat sinks 4 are in contact with the dielectric antenna body 1. The heat sinks 4 are evenly spaced between the protective corner sleeves 3. By arranging a number of wavy heat sinks 4 on both sides of the dielectric antenna body 1, it is possible to accelerate the heat conduction efficiency inside the dielectric antenna, enable the dielectric antenna to dissipate heat quickly in a high temperature environment, and improve the durability of the dielectric antenna. The wavy heat sink 4 has a larger contact surface with the air and can dissipate heat faster.

[0031] Embodiment 3: Circular grooves 6 are provided at the four corners of the bottom of the ceramic base 2, and suction cups 7 are fixedly connected to the inside of the circular grooves 6.

When the inner side of the support sheet 5 is in contact with the protective corner sleeve 3, the bottom height is equal to the bottom height of the ceramic base 2. By arranging the support sheet 5 on the outer side of the protective corner sleeve 3, when the dielectric antenna is installed into the installation groove, the support sheet 5 is pressed to fit with the protective corner sleeve 3, and then installed into the installation groove. The support sheet 5 can exert an outward force on the inner wall of the installation groove, thereby generating friction, so that the dielectric antenna can be installed more securely.

By arranging a plurality of wavy heat sinks 4 on both sides of the dielectric antenna body 1, the heat conduction efficiency of the internal dielectric antenna can be accelerated, and the dielectric antenna can quickly dissipate heat in a high temperature environment, thereby improving the durability of the dielectric antenna. The wavy heat sink 4 has a larger contact surface with the air and can dissipate heat faster.
