The aim of the paper is to propose a fast phase only synthesis (POS) approach to the power pattern synthesis of conformal, shaped-beam reflectarrays, based on FFTs. First, the synthesis approach is described, then the approximation strategy exploited for the FFT-based evaluation of the pattern is discussed, and, finally, the numerical analysis showing the computational advantages is presented.
A new synthesis technique for wideband contoured beam reflectarray antenna is presented. Constraints on the frequency behaviour of the antenna on a prescribed frequency band are enforced and a phase only synthesis approach is adopted. The performances of the presented technique are shown by a wide numerical analysis. The comparison with a standard single frequency synthesis algorithm and with an approach...
