Abstract
This contribution describes the design and simulation results of aparabolic reflectarray antenna to produce multiple spot beams from a geostationary satellite, whichgeneratestwo adjacent beams per feed in orthogonal circular polarization (CP), separated 0.56 degrees,simultaneouslyat 19.7 and 29.5 GHz. The parabolic reflectarray usesa unitcellthatintroducesa progressive phase shift of opposite sign in each CP by applying the variable rotation technique independently atTx(19.7 GHz)and Rx(29.5 GHz) frequencies. The proposed antennacan be suitable for multiple spot beam satellites in Ka-band since itallowsa reduction by a 50% in the number of antennas and feeds needed to provide the multi-spot coverage.
