Abstract :
A novel tri-band CPW-fed antenna designed for RFID applications is reported. Limited to 30 × 30 × mm2 area on a PCBoard with εr = 4.4, the antenna has four U-shaped, two F-shaped and two L-shaped slots as additional resonators to achieve multi-band operation. The intelligent single particle optimisation (ISPO) algorithm is used to determine the optimised slot configuration for the best return loss at 0.92, 2.45, and 5.8 = GHz simultaneously. The performance of the designed antenna was characterised through simulations using the finite element method.
