Abstract
The effect of a dielectric sheet cover on the 
-plane realized element gain pattern of a circular array of axial thin slits is considered. In similar planar arrays, such patterns are characterized by nulls which appear even for spacings less than 
. This phenomenon has previously been linked with the influence of a leaky wave on the near field. It is shown in this paper that, in circular arrays, similar dips occur accompanied by pattern distortions.
