Description
Summary:The design and operation of a small microstrip reflectarray constituted by a conical feed and 81 variable-size double elliptical rings printed on a single substrate and backed by a layer of foam and a conducting ground is presented. The chosen double elliptical rings offer an increased phasing range of unit cells of reflectarray and a higher manufacturing error tolerance. The performance of the designed reflectarray is investigated via full-wave EM simulations and measurements on the manufactured prototype. Both the simulation and measurement results show a wideband performance of the designed reflectarray.
