The study deals with the modelling, practical implementation and characterization of a directional antenna controllable through 360 in the [2 - 2.5 GHz] frequency band. The antenna is composed of a central omnidirectional broadband monopole feed surrounded by a metamaterial made of one or two controllable layers of metallic strips printed on a dielectric substrate, which can be electrically continuous or discontinuous. By controlling the distribution of reflective and transparent regions of the latter metamaterial around the central feed, a directional emission having an angular beamwidth lower or equal to 60 and controllable through 360 is produced in the UMTS and WIFI frequency bands, demonstrating the broadband operation of this antenna.
