based on a resonant meta-surface superstrate is proposed. The behavior
of a single element that is closely placed to a meta-surface is
experimentally investigated. The proposed meta-surface is based
on resonating unit cells formed by capacitively loaded strips and
split ring resonators. By tuning a dipole antenna to the pass band
of the meta-surface, the physical area is effectively illuminated enhancing
the radiation performance. The gain, radiation efficiency
and effective area values of the whole configuration are compared
to the ones obtained with a single dipole without superstrate. Radiation
efficiency values for the proposed configuration of more
than 80% and gain values of more than 4.5 1 dB are obtained.
Based on this configuration, simulated results of a multifrequency
antenna array are presented. Distinctive features of this configuration
are high isolation between elements (20 dB for a distance of lambda0/4), and low back radiation.
