Abstract

The invention discloses an RFID antenna device in the technical field of antenna installation. The RFID antenna device comprises an RFID antenna body and an antenna storage box, and an inner side wallof the antenna storage box is provided with a storage groove for the RFID antenna body. A stretching connection mechanism used for pulling the RFID antenna body out of an outer side of the storage groove and an adjusting mechanism used for enabling the RFID antenna body to rotate up and down are connected between an inner side wall of the storage groove and one side of the RFID antenna body. According to the invention, an RFID antenna can be dismounted and mounted conveniently, and the signal coverage range of the RFID antenna can be adjusted by pulling out the RFID antenna and adjusting therotation angle when the RFID antenna works.

Description

technical field [0001] The invention relates to the technical field of antenna installation, in particular to an RFID antenna device. Background technique [0002] RFID system antennas are generally divided into two categories: electronic tag antenna design and reader antenna. The antenna design of RFID systems in different working frequency bands has its own characteristics. For LF and HF frequency bands, the system uses inductive coupling to work. The working energy required by the electronic tag is obtained by inductive coupling from the near-field radiation of the coupling coil of the reader. It is generally a passive system and the working distance is small, not greater than 1 rice. In fact, the near field of the reader does not involve the problem of electromagnetic wave propagation, and the antenna design is relatively simple. [0003] When the existing RFID antenna is installed, it is usually only directly fixed to the installation surface, which easily leads to d...
