| Outline of Final Research Achievements |
To shape radiation patterns of mobile base station antennas, this study proposes replacement of the antenna radome by a metamaterial lens for simplicity of antenna configuration. The lens shape is designed by ray tracing method. The radome diameter can be reduced by using negative refractive index lens. To achieve the metamaterial radome, small metamaterial structure composed of multilayer ceramic capacitors in the cutoff waveguide is proposed. The design method and insertion loss characteristics are shown. Three-dimensional dielectric metamaterial structure is fabricated.
