This contribution proposes the use of dual reflectarray (RA) configurations to provide multi-spot coverage in Ka-band from a geostationary satellite, using a smaller number of apertures and feeds than conventional reflector systems. A dual-RA configuration formed by a parabolic main RA and a flat RA subreflector has been designed to produce two spot beams in orthogonal circular polarization (CP) from a single feed in dual linear polarization (LP). The flat RA subreflector provides the required angular separation between the beams by implementing a different phase distribution in each LP, while the parabolic main RA performs the conversion from dual-LP into dual-CP. The simulated results show the feasibility of the proposed configuration and its potential to be used for multiple beam applications in Ka-band. | |
