Abstract :
In this paper, first, the idea of using reactive impedance surfaces (RISs) as the ground plane of such leaky wave antennas is proposed and studied through a few examples. Next, the effect of a typical source antenna position on the directivity is investigated through a parametric study. Then, the radiation characteristics of these different antennas are determined and compared. Finally, the conclusion is drawn
