Abstract
This contribution describes the design and simulation results of a parabolic reflectarray antenna to produce multiple spot beams from a geostationary satellite, which generates two adjacent beams per feed in orthogonal circular polarization (CP), separated 0.56 degrees, simultaneously at 19.7 and 29.5 GHz. The parabolic reflectarray uses a unit cell that introduces a progressive phase shift of opposite sign in each CP by applying the variable rotation technique independently at Tx (19.7 GHz) and Rx (29.5 GHz) frequencies. The proposed antenna can be suitable for multiple spot beam satellites in Ka-band since it allows a reduction by a 50% in the number of antennas and feeds needed to provide the multi-spot coverage.
