Label antenna suitable for IT device

Abstract

The invention relates to a label antenna suitable for an IT device and belongs to the wireless radio frequency device field. The label antenna is characterized in that the label antenna comprises a radiation patch, a dielectric substrate and a coaxial feeder; the radiation patch is arranged on the dielectric substrate and is attached to the dielectric substrate; the size of the dielectric substrate is greater than that of the radiation patch; a distance from the edge of the radiation patch to the edge of the dielectric patch is more than 3 cm; the coaxial feeder is vertical to the radiation patch and the dielectric substrate; the coaxial feeder is vertically connected with the radiation patch; and the coaxial feeder is embedded in the dielectric substrate. The label antenna has a mobile communication terminal interference-resisting ability. The input impedance matching of the label antenna is excellent. Design requirements can be greatly satisfied. The structure of the designed antenna is simple. The mass production of the antenna can be realized easily. The antenna has a bright application prospects.

Description

technical field [0001] The invention belongs to the field of radio frequency devices, in particular to a tag antenna suitable for IT equipment. Background technique [0002] With the rapid development of the economy and the increasing number of communication equipment, manual registration is required in traditional asset management, and the status of equipment cannot be detected in real time. Accounts, cards, and objects do not match. In order to solve problems such as repeated purchases or idleness, scholars have proposed solutions based on RFID tag technology, and many companies have developed RFID fixed asset management systems. However, during the application process, due to the low reading rate, small reading range, and susceptibility to interference of RFID tags, it is difficult to promote and popularize, and there are many faults in the built system, which seriously affects normal use. IT assets generally refer to computers and network equipment placed in offices and...

AI Technical Summary

Problems solved by technology

The reflected wave generated on the metal and the strong absorption of the human body can cause the tag to fail to work. The electromagnetic stray interference caused by the mobile communication system reduces the reading distance of the reader and reduces the signal-to-noise ratio of the input terminal of the tag chip.
