In this paper, a square-shaped microstrip passive RFID tag suitable for wall mount in RFID localization systems is presented. The tag antenna is designed for the ultra-high frequency (UHF) band and is excited by a dual inset feed network to achieve circular polarization (CP). A cross slot is embedde...
