Abstract: A novel 2D-beamsteering technique employing a metamaterial transmitarray is presented. The proposed transmitarray, when coupled to a conventional horn antenna, allows its original radiation pattern to be steered in both elevation and azimuth planes. A fixed 25º steering in θ and ϕ (spherical coordinates) was achieved through electromagnetic simulations and validated against experimental results, obtained from a prototype comprised of 5 x 5 unitcells at 5.35 GHz, carried out inside an anechoic chamber.
