Abstract
[ENG]Re ectarray antennas o er an attractive alternative solution to both re ector antennas and antenna arrays. These
antennas have attracted signi cant attention in space applications thanks to their low mechanical complexity and their
lack of a complex feeding network. Re ectarray antennas consist of a re ector antenna whose parabolic re ector is
replaced by a planar surface. This re ectarray surface consists of isolated radiating elements, and it is illuminated by
a feeder located away from the surface. These isolated radiating elements are pre-designed to manipulate the features
of the radiated beam in terms of direction, beamwidth, polarization, etc. The key element of re ectarray beamforming
is the phase shift introduced by each unit-cell, which is obtained by varying some of the geometrical parameters of the
unit cell itself. The design of the re ectarray utilizes re ection phase design curves. Various elements have been used for
the synthesis of re ectarrays, such as ...
