In this contribution, the design of spherical reflectarray antennas is proposed to achieve a compromise between parabolic and spherical surfaces. The spherical surface simplifies the folding mechanism of the antenna, while the printed elements on the reflectarray surface are designed to correct the spherical aberration, improving the focusing of the spherical surface and providing the electrical performance of a parabolic reflector antenna. The focusing and scanning capabilities of spherical reflectarrays are evaluated and the implementation of spherical reflectarrays in dual antenna configurations is proposed to provide further compact antenna solutions.
