Abstract

A reflectarray antenna capable of operating independently in the transmit frequencies (from a satellite) in Ku-band (11-13 GHz) and Ka-band (19-20 GHz) has been proposed and demonstrated. To prove that independent beams can be optimized in each frequency band using separate feeds, a 25-cm demonstrator that generates a focused beam in dual polarization (linear or circular) has been designed, manufactured, and tested. The reflectarray cells comprise two stacked sets of coupled parallel dipoles for each polarization, which permits an independent optimization of the phase for each frequency and polarization. The simulated and measured radiation patterns for both copolar and crosspolar components are in good agreement in Ku- and Ka-bands.
