Abstract :
This paper presents two new compact designs of dual printed meander monopole antennas for passive UHF RFID tags that operate with multi-port RFID chips. The designed antennas have a smaller footprint in comparison with the commonly used dual dipole-type antennas thus reducing the area needed for the RFID tag. For maximum power transfer to the chips and conjugate impedance matching, the antennas are inductively-coupled with printed loops. A compact tag prototype is fabricated with the area of only 51 mm × 43 mm using a Rogers RO4350B substrate with the thickness of 1.524 mm. Experimental results demonstrate achieving a maximum readable range of 8.65 m.
