Item type:Publication, Design of flat spiral rectangular loop gate antenna for HF-RFID systems(2008-12-01); Torrungrueng, DanaiThis paper presents a flat spiral rectangular loop gate antenna in walk-through gate installation for improving the distribution of magnetic field in High-Frequency Radio Frequency Identification (HF-RFID) systems. The spiral structure can provide the magnetic field distribution to cover desired region in various directions. This antenna is designed as a walk-through gate for the anti-theft application. The prototype antenna was fabricated and measured to confirm the antenna performance. ©2008 IEEE. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Improvement of communication performance for trapezoidal dual loop antennas by switching techniques(2007-12-01); Torrungrueng, DanaiThis paper presents the switching techniques for trapezoidal dual loop antennas to improve the communication performance of Radio Frequency Identification (RFID) system at low frequency. The switching techniques use two sets of antennas in walk-through gate configuration in order that the RFID reader can activate two sets of antenna at different times. Both antennas were designed to yield the magnetic field covering the entire volume. The antenna prototype was fabricated and measured the percentage of volume to confirm the communication performance. The obtained percentages of volume in three principal axes are 100%. The experimental results verify the antenna capability in RFID system.
