Abstract :
In this paper, a new metamaterial-based printed antenna for UHF Radio Frequency Identification (RFID) Readers is presented. This antenna is designed such that several can be connected in series to provide local RFID coverage. In this work, simulation and measurements are shown to agree very well and that confined UHF communication can be achieved with this antenna. Furthermore, the geometry of the new metamaterial-based UHF RFID antenna is altered and the resonant frequency is computed using simulations. It is shown that by varying certain geometrical features of the array, the operating frequency can be increased and decreased in a predictable manner.
