Abstract :
This paper proposes new reflectarray elements for dual-polarization and wideband use. These elements provide liner phase property with the same slope characteristics for dual polarization, thereby achieving the desirable reflection phase over wide frequency range. The usefulness of the proposed elements is verified by comparing between the calculated reflection phase for periodic reflectarray and the measured one. Finally we present an offset reflectarray designed by using the proposed elements, and also confirm wideband frequency characteristics numerically and experimentally.
