Characteristics of a meander line tag antenna with T-Loop structure for the passive UHF RFID Applications

The meander line tag antenna with T-Loop structure is presented for Radio Frequency Identification (RFID) system according to the national standard of UHF RFID along the frequency range of 920-925 MHz. The size of the proposed tag antenna is approximately 88 mm × 10 mm, and it is designed by using NXP G2XL IC chip in TSSOP8 package with the impedance of 16.08-j148.7 ω at the frequency of 922.5 MHz. The antenna characteristics such as impedance characteristics and radiation pattern are analyzed. © 2012 IEEE.
