Design of small antennas based on DNG metamaterials

Abstract

Two double negative (DNG) metamaterial antennas are presented. The design of the unit cell of each one of the two antennas is based on the composite right/left-handed (CRLH) transmission line (TL) model. Two designs are introduced using single and double layer structures. The dispersion diagrams of the proposed antennas are evaluated and the resonant frequencies of the different modes in the RH and the LH ranges are determined from the dispersion diagrams. Field animations of the near field below the patches and near the vias for different modes will be presented.
