“…For the sake of simplicity, a generic E field component and template T were used in (16) and (17), but they should be applied to the co-polar and cross-polar components of both polarizations with their respective normalized templates. The result of the forward projection, E (u, v) given by eq.…”

“…From there, the matrix of reflection coefficients are computed, which fully characterize the reflectarray element. In [16] another faceted reflectarray is designed using a different approach. The reflectarray is directly optimized [17] using a gradient-based minimax algorithm and it also uses a phase-only synthesis as starting point, but in this case the initial reflectarray phase distribution is retrieved from a shaped reflector design.…”

“…It should be stated that the bandwidth can be limited in the case of large-sized RAs due to the wide variation range of path lengths between the feed and the RA elements. These path delays must be compensated over the frequency band by the RA elements [18]. A parabolic RA made of multi-flat facets was designed for contoured beam antenna [18], [19] to solve the path delay issue.…”

“…These variations can also be compensated by the use of facetted configurations approximating a paraboloid [37], [38], or by directly printing the reflectarray elements on a parabolic surface [39]. It has been shown that these configurations improve the reflectarray bandwidth, but the cross-polarization is penalized by the inclination of the panels or by the offset parabolic surface.…”

“…38 shows the evolution of gain with frequency in each polarization for both measurements and simulations, considering first the nominal values of εr and tanδ of the two dielectric materials, and then, the corrected values. The radiation patterns were also measured at 18 GHz in order to obtain a more complete characterization of the antenna operation in the upper band.…”
