Abstract

A method for implementing a highly directional directional RFID tag, characterized in that the method uses a dielectric substrate, a directional coupler, an RFID tag chip, and a filter in the RFID operating frequency band, wherein the dielectric substrate is used to carry and fix the directional coupler, RFID tag chip, filter in the RFID working frequency band; the directional coupler is connected to the signal input end to realize coupling with the input signal; the signal output end of the directional coupler is connected to the filter in the RFID frequency band, and the signal passed through the filter is connected to the RFID tag The + pin of the chip grounds the - pin of the RFID tag chip; the invention realizes the orientation of the RFID tag through a directional coupler, and reduces the coupling of the reflected signal in the working frequency band through the adjustment of the resistance in the directional coupler, satisfying Directivity requirements for RF devices and RF systems. This makes the highly directional RFID tag suitable for use in wired systems in the field of mobile communications.

Description

【Technical field】 [0001] The invention relates to the field of a network composed of passive devices and the Internet of Things, and in particular to a method for realizing a highly directional directional RFID tag. 【Background technique】 [0002] The so-called RFID technology refers to a non-contact radio frequency automatic identification technology, which automatically identifies the target object and obtains relevant data through radio frequency signals. The identification work does not require manual intervention and can work in various harsh environments. The RFID tag refers to a marker that can be identified by radio frequency. Current RFID tags generally use dipole antennas, which do not have directivity and signal selectivity, which makes it impossible for RFID technology to perform directional detection of signal input and output detection and callback loss in wired systems in the field of mobile communications. [0003] Based on this, it is necessary to provide a...
