Abstract

The invention discloses a misread-preventing antenna. The antenna comprises a copper sheet, a substrate and a feeder line part in stacking arrangement; the feeder line part comprises an antenna radiation micro-strip line, a shielding unit and a matching element; the antenna radiation micro-strip line comprises an input micro-strip line, two sections of micro-strip line units symmetrically arranged at two sides of a horizontal center line of the substrate, and an output micro-strip line which are connected in order; the micro-strip line unit comprises a first regulating part, a second regulating part and a third regulating part which are connected in order; the gap is formed between the radiation micro-strip line and the matching element so as to form parasitic inductance to realize the capacitive coupling; the shielding unit forms a feeder line outer ring for covering the feeder line part, thereby shielding external electromagnetic interference and shielding a coupling signal leakage periphery. The invention can provide a misread-preventing antenna which is stable in performance, controllable in antenna recognition signal range, and free from blind point.

Description

technical field [0001] The invention relates to the technical field of near-field antennas, in particular to an anti-misreading antenna. Background technique [0002] At present, the RFID industry has begun to be widely used in many fields such as logistics, transportation, and clothing. The RFID system consists of RFID readers, RFID electronic tags and antennas. The RFID system works in three main processes: 1. The system activates the tag process, 2. The tag feeds back the status process to the system. 3. The system processes the label information and modifies the label information process. Tags, antennas, and reading and writing systems form a complete closed-loop communication link. The reader has the ability to identify multiple electronic tags at the same time in batches, and the tags can be effectively identified within a certain area covered by the signal of the reader. In some special applications, the RFID system needs to cover the RFID radio frequency signal in ...
