Description

technical field [0001] The invention belongs to the technical field of electronic tag antennas, in particular to a ceramic electronic tag antenna rapid test frequency modulation device and a ceramic electronic tag antenna rapid test frequency modulation method. Background technique [0002] At present, most of the electronic tag test equipment adopts the inductive test method, that is, the non-contact test method. The antenna is placed under the metal pole erected horizontally. The distance between the antenna and the horizontal metal pole depends on the size of the antenna itself. The larger the antenna size The farther away from the metal pole, the smaller the size of the antenna, the closer the distance to the metal pole. The test principle is: the horizontal metal pole has a certain distance from the metal reflector in the vertical direction, and the general height is 2 to 5 times the thickness of the antenna under test. The horizontal metal rod is connected to the test ...

AI Technical Summary

Problems solved by technology

[0003] However, the disadvantages of this test tool are: 1. The antenna under test needs to be placed horizontally and in close contact with the metal reflector during the test, which may easily cause scratches on the surface of the antenna and wear on the surface of the reflector;

[0004] 2. If tiny impurities such as dust or wool fibers fall between the surface of the metal reflector and the surface of the antenna under test, it will cause the test frequency to shift, and a slight deviation in the angle and position of the antenna will cause a large frequency test error;

[0005] 3. When the test frequency deviates from the target frequency, it is necessary to trim the physical size of the surface electrode with an electric grinding head. The common problem is that each antenna needs to be picked up and put down for repeated debugging 3 to 5 times before the frequency can be trimmed in place. For each test, the antenna needs to be placed horizontally and in good contact with the reflector. In actual operation, friction will occur between the antenna surface and the reflector. The more times of debugging, the lower the production efficiency, and the more scratches will be caused on the contact surface between the antenna and the reflector. Many, and reduce the service life of the reflector;

[0006] 4. Ceramic electronic tags tend to be miniaturized. The antenna is small, and it is inconvenient to place it manually. The antenna cannot be fixed stably. The defect rate during debugging will also increase, which will affect production efficiency.
