A new type of annular patch antenna is presented. At variance of classical annular patch antenna the inner cylindrical wall is metallized. It radiates as a circular patch but has a smaller stored energy and the feed point can be chosen to have an easy matching. A cavity model approach of the patch antenna is presented; the theoretical results are compared with the experimental ones.

Abstract
A new type of annular patch antenna is presented. At variance of classical annular patch antenna the inner cylindrical wall is metallized. It radiates as a circular patch but has a smaller stored energy and the feed point can be chosen to have an easy matching. A cavity model approach of the patch antenna is presented; the theoretical results are compared with the experimental ones.
