In this paper, a novel thin card-sized on-metal 953MHz UHF RFID tag is presented. The RFID tag operates in a unique configuration with an IC chip mounted on a small metallic loop and a radiative mushroom structure. A card-sized 54×86×0.94mm3 tag is designed successfully with a reasonable IC impedance matching with appropriate loop dimensions. It is shown that the reading range performance is tolerant of the environment and the measured reading range is 2.6m on a large 200×300×2mm3 metal board. The reading range is 0.1m longer than a commercial card-sized on-metal tag with much larger thickness of 1.8mm.
