  • Abstract
    The reason for the presence of unwanted sidelobes in multifeed single-beam reflectarrays and power combiners is shown to be a grating lobe phenomenon due to “amplitude clustering” of the scattered field over the reflectarray aperture. A means of controlling the level of these lobes is proposed and validated using full-wave analysis and measurements.
