The Crab label tag with a loop matching feed and a modified dipole antenna structure was proposed. The antenna impedance is conjugated easily to a radio frequency identification IC chip impedance by a loop matching feed. The reading range of the crab structure tag is 0.9?1.0 m from the upper side of the formula milk can lid. The fabricated label tag size is 44.0 × 44.0 ㎟. The operating frequency at -3 ㏈ return loss is 861.0?929.0 ㎒, and the maximum reading range at the anechoic chamber is 1.5 m.
