Abstract :
In the High Frequency band, antennas for Over-The-Horizon (OTH) applications suffer from the uncontrolled radiation of surface waves. We propose here to load antennas with metamaterial in order to control surface waves. As a consequence, the energy wasted in unwanted propagation mode is reduced and the coverage of radars or communication systems using those antennas is improved.
