An Innovative Miniature UHF RFID Tag Antenna Applied for Metal Surface

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 293)


This paper proposes a novel miniature RFID tag antenna used in metal surface structure for UHF radio frequency identification systems. The antenna is designed in the FR4 substrate with size of 18 × 18 × 1.6 mm3. Antenna structure includes two metal trimmed radiators where two short-circuit connected to metal ground plane designed for reducing the interference of the metal surface and two symmetrical zigzag strips to reduce the size of the antenna. Four L-shaped strips and two cutting triangles are added to adjustment conjugate impedance. The antenna 10 dB impedance bandwidth, from 793 to 979 MHz, is suitable for UHF RFID applications.
