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.
