Abstract: A wideband reflectarray antenna for dual polarizations application is formed by an array of phasing cells, where each cell contains two orthogonal or quasi-orthogonal sets of parallel conductive dipoles printed on two levels of a multilayered grounded substrate. The dipoles for each polarization are coupled in both horizontal and vertical directions, providing a large broadband operation and low cross-polarization with only two levels of metallizations. The antenna is designed by adjusting the lengths of the dipoles to produce the phase-shift required to collimate or shape the radiated beam in dual-polarization when illuminated by a feed, either in broadband or dual-frequency operation. The invention also relates to a design and manufacturing method for producing the reflectarray antenna, based on the optimization of the dipole lengths for each phasing cell.
