Abstract :
The metamaterial structure composed of cubic high dielectric resonators periodically arrayed in a low dielectric substrate is analysed and a flat metamaterial lens is used to improve the gain of a rectangular patch antenna. A dielectric slab is also discussed and compared with the metamaterial lens. Experimental results show that the proposed metamaterial flat lens can improve the gain of a patch antenna remarkably at both the first and the third resonant mode.
