A two-layer reflectarray made of varying-sized patches on a parabolic surface is proposed in this paper to enlarge the bandwidth for shaped-beam antennas in telecommunication missions. The beam is focused by the parabolic surface, while the phasing on the reflectarray is used to generate the required contoured beam. A technique for the analysis and design of the parabolic configuration is presented,...
In this contribution, a reflectarray is proposed as subreflector in a dual-reflector configuration to produce a contoured beam for DBS applications. The beam shaping is obtained by adjusting the phase on the reflectarray elements. In order to analyse the antenna, a modular technique has been developed so that the most appropriate analysis method is used for each element of the structure: full-wave...
