A Printed Reflectarray with Annular Patches

Abstract

In this paper an example of Printed Reflectarray, designed to validate the concept of the use of annular patches, will be analyzed and discussed. The analysis of the structure and the computation of the phase curves for the field reflected from the patches, needed for the design of the elements, have been carried out with full wave methods taking into account the interaction among the elements. The reflectarray sample is a 5x5 elements structure, and the results have shown good pattern behavior and symmetry.
