This paper presents an accurate analysis of different configurations of eflectarrayre sonant elements that can be used for the design of passive and tunable reflectarrays. Rdection loss and bandwidth performances of these reflectarray elements have been analyzed in the X-band frequency range with the Finite Integral Method technique, and the results have been verified by the waveguide scattering parameter measurements. The results demonstrate a reduction in the phase errors offering an increased static linear phase range of 22Y which allows to improve the bandwidth performance of single layer reflectarray antenna. Moreover a maximum dynamic phase range of 320' and a volume ~eductiono f 22.15% have been demonstrated for a 10GHz reflectarray element based on the use of rectangular patch with an embedded circular slot.
