Design of an UHF RFID Anti-metal Tag Antenna
摘要
Based on a microstrip structure, an ultra-high frequency (UHF) radio-frequency identification (RFID) tag antenna working on a metal surface has been designed in this paper. An H-shaped slot structure and two U-shaped slots are embedded on its radiation patch in order to reduce its resonant frequency and achieve impedance conjugate matching with the chip. Through HFSS simulation, its optimized dimensions are given as 66mm×25mm×2mm, and its reading distance on a metal surface can reach 7.1metres. Compared with other anti-metal tag antennas, this antenna performs quite well in terms of overall performance parameters.
