Radiation performances of a dipole array configuration inserted in a left-handed media

Abstract

In this work, the radiation improvements achieved when Left Handed Media (LHM) are combined with dipole antennas has been analysed. The behavior of two dipole antennas in array configuration when a Left Handed superstrate and substrate are placed over and under them has been analysed. Different positions of the dipoles have been studied. Besides, dielectric losses and copper SRRs and CLSs have been taken into account for different distance between dipoles in order to analysed their influence in the radiation properties. Simulation results are presented showing high efficiency antennas with enhanced gain patterns.
