Design of the Crab label tag with a loop matching feed and a modified dipole structure at 900 MHz Choi, Eui-Sun; Lee, Hak-Yong; Lee, Jin-Seong; Lee, Kyoung-Hwan; Lee, Sa-Won; Lee, Young-Hie;
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 . The operating frequency at -3 dB return loss is 861.0-929.0 MHz, and the maximum reading range at the anechoic chamber is 1.5 m.
