© 2016 European Association of Antennas and Propagation. It has been demonstrated that metamaterial-inspired electrically small antennas (ESAs) can be designed to have high radiation efficiencies and even large bandwidths with non-Foster circuit augmentations. However, being electrically small, it still remains a challenge to obtain directivities over interesting bandwidths which exceed those of simple dipoles, especially with only passive constructs. Different classes of metamaterial-inspired ESAs that have successfully produced higher directivities will be reviewed and new configurations will be introduced and discussed.
