The design of a locally one‐dimensional inductive‐varying metamaterial operating near 10 GHz is reported. This is combined with a fixed capacitive grid to design a phase‐varying metasurface. This composite metasurface is then used as a partially reflecting surface (PRS) together with a perfect electric conductor surface to form a resonant Fabry‐Pérot type cavity. A patch antenna acting as a primary source is embedded in the cavity to constitute a highly beam‐steerable directive antenna. A 56° deflection of the antenna beam is experimentally observed.
