Abstract
A method of manufacturing a cellular reflectarray antenna arranged in an m by n matrix of radiating elements for communication with a satellite includes steps of determining a delay φm,n for each of said m by n matrix of elements of said cellular reflectarray antenna using sub-steps of: determining the longitude and latitude of operation, determining elevation and azimuth angles of the reflectarray with respect to the satellite and converting theta(θ) and phi(φ), determining Δβthe pointing vector correction, for a given inter-element spacing and wavelength, determining Δφ, the spherical wave front correction factor, for a given radius from the central element and/or from measured data from the feed horn; and, determining a delay φm,n for each of said m by n matrix of elements as a function of Δβand Δφ.
