Reflectarray antennas for space applications

Abstract

In this paper, the advantages and recent developments of reflectarray antennas for space applications are reviewed. Basic requirements for space antennas, and the limitations and challenges of conventional designs are discussed. Various advantages of reflectarray antennas over reflectors and phased array antennas are reviewed and it is shown that reflectarray antennas can be a suitable low-cost choice for the new generation of space antennas.
