Abstract :
In this paper it is shown, that reflectarrays have inherent advantages over parabolic reflector antennas and, hence, there is interest in using these antennas as replacements for standard reflectors. Numerical investigations of reflective type antennas with flat reflectors are discussed. Also, we have measured the scattering parameters of controllable microstrip reflectarrays. The research can be used to develop antennas with optimum parameters.
