Tiivistelmä
A novel low-profile metal mountable UHF RFID tag antenna is presented. The tag antenna design consists of two resonating patches with different resonant frequencies fed through a joint inductive loop. This design topology offers benefits such as bandwidth enhancement in the single band and the possibility of attaining a tunable dualband coverage in the UHF RFID band. The proposed antenna structure doesn't require any electrical connection (shorting pins/shorting plates/via holes) and therefore facilitates fabrication through a conventional RFID inlay manufacturing process. Fabrication and testing of a prototype of the proposed antenna design are carried out. The prototype antenna achieves free space and an on-metal reading range of better than 8 m and 11 m respectively in the US RFID band of 902-928 MHz.
