Abstract

This paper investigates the design of UHF RFID tagging antennas mounted on, or in close proximity, with a conducting surface. Detailed simulation and analysis of the tag antenna was carried out for 900 MHz operation. The antenna dimensions were fixed at 32.5 mm × 9.5 mm × 1.6 mm. From simulation the input impedance of the target transponder antenna was found to be (14.3-j140.9) Ω, normalized to 50 Ω. The final design was tested to identify an object consisting of a metal surface, the effective detection was found to be between 0.7 m and 1.2 m.
