Abstract

The invention discloses a near field adaptive focusing antenna applied to an RFID. The antenna comprises an antenna casing body, an antenna circuit module and a base. A mounting board is arranged on the base. The antenna circuit module is connected with the mounting board through a buffer mechanism. The base abuts against the port of the antenna casing body and is connected with the antenna casingbody through four connecting mechanisms. Four mounting blocks are arranged on the base. A prompting patch is arranged on the upper end face of the antenna casing body. The antenna circuit module is provided with an external connector which is electrically connected. The external connector penetrates the antenna casing body and is movably connected therewith. The buffer mechanism comprises four T-shaped rods fixed on the mounting board. The connecting plate is arranged on the upper side of the mounting board. Four T-shaped rods all run through the connecting plate and are slidably connected therewith. According to the invention, the structure is reasonable, facilitates installation and disassembly of the casing body, and is convenient for a worker to maintain the structure; and buffer protection is provided for the antenna circuit module to improve the service life thereof.

Description

technical field [0001] The invention relates to the technical field of RFID adaptive focusing antennas, in particular to a near-field adaptive focusing antenna applied to RFID. Background technique [0002] Radio Frequency Identification (RFID) is a wireless communication technology that can identify specific targets and read and write related data through radio signals without establishing mechanical or optical contact between the identification system and specific targets. [0003] Radio signals transmit data from a tag attached to an item through an electromagnetic field tuned to a radio frequency to automatically identify and track the item. Some tags can get energy from the electromagnetic field emitted by the identifier during identification, and do not need batteries; there are also tags that have their own power supply and can actively emit radio waves (electromagnetic fields tuned to radio frequencies). Tags contain electronically stored information and can be iden...
