Abstract :
This paper presents the theoretical analysis and experimental testing of three compact microstrip patch antennas designed for the Radio Frequency Identification (RFID) Readers in the Ultra High Frequency (UHF) band of 865-868 MHz. The characteristics and performance of the new miniaturized antenna is compared to a conventional quarter wave patch antenna and an enhanced truncated square patch with shorting pins. The proposed patch antenna is compact and measures 80 mm by 70 mm along with its ground plane. Due to its dual circular polarization, it offers a read range of up to 9 feet for horizontal and vertical tag orientation. A simple and novel technique to miniaturize the antenna for the ever increasing RFID applications is presented in this paper.
