Resumen
In this paper, the radiation performances of different antenna configuration
based on Left-Handed superstrates are presented. First of all, the behaviour of a Left-
Handed (LH) unit cell is analysed, showing a resonant response with pass band and stop
band frequencies. In order to improve the radiation performances of a single dipole, ie.,
to increase the directivity and efficiency and to red ...

In this paper, the radiation performances of different antenna configuration
based on Left-Handed superstrates are presented. First of all, the behaviour of a Left-
Handed (LH) unit cell is analysed, showing a resonant response with pass band and stop
band frequencies. In order to improve the radiation performances of a single dipole, ie.,
to increase the directivity and efficiency and to reduce the back radiation, diverse LH
superstrates working at the resonant frequency of the dipole are analysed. With these
configurations, improvements in terms of directivity higher than 6 dB with efficiency
closer to 100 % have been obtained. [--]
