Abstract: In this talk, we review the historic development of Fresnel zone antennas and reflectarrays. The strong relationships between these two antennas are discussed. It is shown that many of the limitations of reflectarrays and possible methods for improvement are strongly related with the theory of Fresnel zone antennas. We overview the recent advances of reflectarrays and provide our thinking on possible future research directions.
