Reflectarrays analysis is carried out by computing a specific phase curve as a function of the length of the single radiating element. Moment Method approach is integrated with physical optics solution for taking into account the effect of the finite ground plane. The different incidence angles on the reflectarray elements are also considered in the evaluation of the phase design curve. A synthesis algorithm based on the iterative projection approach is adopted to obtain a radiated field with a prescribed beam direction. Numerical results on two 10GHz offset fed reflectarrays with 17x17 patches are presented.

Abstract
Reflectarrays analysis is carried out by computing a specific phase curve as a function of the length of the single radiating element. Moment Method approach is integrated with physical optics solution for taking into account the effect of the finite ground plane. The different incidence angles on the reflectarray elements are also considered in the evaluation of the phase design curve. A synthesis algorithm based on the iterative projection approach is adopted to obtain a radiated field with a prescribed beam direction. Numerical results on two 10GHz offset fed reflectarrays with 17x17 patches are presented.File in questo prodotto:
