Abstract :
In this paper, a slot coupled dipole antenna was presented for dual band passive RFID tag applications. Structures using a slot coupled feed and a resonator are explored to achieve dual band operation. It shows good impedance and radiation characteristics from 860 MHz to 960 MHz (ISO 18000-6) and from 2.40 GHz to 2.50 GHz (ISO 18000-4). The return loss is verified by comparing the calculations and measurements, which show good agreement. Radiation patterns are omni-directional for operation frequencies. Numerical results are calculated using Ansoft HFSS (High Frequency Structure Simulator)
