Abstract
In this paper layout of long detection range radio frequency identification tag antenna mountable on metallic surface is presented. This tag antenna layout consists of two non-connected L-shaped load bars and two sectorial patches electrically connected through seven pairs of vias and conducting rear-plane to form a loop antenna. This proposed tag antenna can be tuned in wide range for impedance matching and introduces circular polarization. The tag antenna characteristics are also measured on metal plate. The results show that maximum detection range of the specimen, placed on metallic plate found to be 8.4 ms. The measured 10 dB bandwidth of circular tag antenna is 17 MHz (906–923 MHz) with simulated 3 dB axial ratio bandwidth of 13 MHz. This circular tag antenna is simulated with 4 W EIRP reader.
期刊介绍:
Analog Integrated Circuits and Signal Processing is an archival peer reviewed journal dedicated to the design and application of analog, radio frequency (RF), and mixed signal integrated circuits (ICs) as well as signal processing circuits and systems. It features both new research results and tutorial views and reflects the large volume of cutting-edge research activity in the worldwide field today.
A partial list of topics includes analog and mixed signal interface circuits and systems; analog and RFIC design; data converters; active-RC, switched-capacitor, and continuous-time integrated filters; mixed analog/digital VLSI systems; wireless radio transceivers; clock and data recovery circuits; and high speed optoelectronic circuits and systems.
