Beam-scanning reflectarray based on a single varactor-tuned element

Abstract

A single varactor-tuned element is investigated as effective solution for the realization of reconfigurable reflectarray antennas. The proposed configuration is successfully implemented for the design of an X-band reflectarray prototype of 3×15 radiators. A dedicated electronic control board is designed as an integral part of the antenna. Good performances in terms of beam-scanning capabilities are obtained from measurements. Copyright © 2012 F.
