Title:
METHOD FOR CONTROLLING TAG IDENTIFICATION RANGE OF ULTRA-HIGH FREQUENCY NEAR-FIELD RFID SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/179017
Kind Code:
A1
Abstract:
A method for controlling a tag identification range of an ultra-high frequency near-field RFID system. The method for controlling a tag identification range of an ultra-high frequency near-field RFID system comprises the following steps: using a non-near-field antenna or a combination of non-near-field antennas to connect an ultra-high frequency RFID reader as a feed source; and using a half-wavelength conductor as an infrastructure unit, and exciting the infrastructure unit by using the feed source, so as to form an effective identification range of an ultra-high frequency RFID system around the half-wavelength conductor, the effective identification range being used for identifying an ultra-high frequency near-field RFID tag. The use of the method for controlling a tag identification range of an ultra-high frequency near-field RFID system can accurately control an identification range of an electronic tag.
