Abstract

Computer Science Computer Science, Interdisciplinary Applications Engineering Engineering, Electrical & Electronic Science & Technology Technology
This paper presents a compact (35x36.5 mm) RFID tag antenna which has large RCS patterns and easy conjugate impedance matching property by use of an inductively-coupled feeding. Its simulated maximum (match state) and minimum (short state) RES are -15.36dBm(2) and -22.0 dBm(2) with a difference of 6.69 dB between the two states. We have also calculated the detection distance of the tag for different values of reader antenna gain.
