Design of a multi-band metamaterial-inspired dipole antenna with director element

Abstract

In this work, we present a multiband metamaterial-inspired antenna. The proposed structure consists of a printed dipole antenna with two Split Ring Resonators (SRRs) and one director element. The addition of the resonators and the director leads to new resonance frequencies lower than that corresponding to the dipole alone with different radiation patterns. Simulation and measured results of return loss and radiation patterns are presented and analysed.
