| Summary: | In the 5G mobile system, a service area of one base station is covered by many multi baems. So, abase station antenna must produce multi beams. For the convenience of achieving multi beam, a sylindrical lens antenna was proposed. Features of this configuration are simple configuration of using one feed for one beam, achieving low side lobe characteristics by lens shaping and ease of achieving multi beam by multi feed arrangement. In this paper, some design examples of lens shapes are summarized. Lens shapes are strongly dependent on refractive index values such as positive and negative. In the case of a positive refractive index, lens shape becomes convex. In the case of a negative refractive index (metamaterial) , lens shape becomes concave. Because the concave lens can form very slender antenna shape, the metamaterial lens is considered to be suitable for a base station antenna. |
