Abstract
A broadband reflectarray element is proposed for dual-polarization. The element consists of two orthogonal sets of three coplanar parallel dipoles. Each set of coplanar parallel dipoles is used for controlling the phase-shift for each polarization of the incident electric field. A home-made software based on the Method of Moments in the Spectral Domain (MoM-SD) has been used to compute the phase, losses and cross-polarization performance of the reflectarray element in a periodic environment. This software is a powerful numerical tool for the design of dual-polarization reflectarray antennas under the local periodicity assumption. The results obtained with the home-mode software have been compared with results provided by the commercial software CST®, and excellent agreement has been found. Also, significant CPU time savings can be achieved with our software by comparison with CST®. The dual-polarization element proposed in this paper has proven to show a broadband and low loss performance.
