Abstract The design of a microstrip reflectarray formed by 81 variable size double elliptical rings illuminated by a conical feed is presented.Because of double resonance, the double elliptical rings provide an increased phasing range of unit cells that exceeds the required minimum of 360°. Printed on a single substrate and supported by a layer of foam and a conducting ground, they also offer a slow phase slope as a function of their size, and thus provide an increased operational bandwidth and a good manufacturing error tolerance. The performance of the designed reflectarray is investigated via full-wave electromagnetic simulations and measurements on the manufactured prototype. The presented results show a wideband performance of the designed reflectarray.
