| Outline of Final Research Achievements |
For the beyond 5G system, ultra high speed data transmission should be developed. This research presents the design of beam scanning area of optical multi-beam antenna for indoor wireless system. Large propagation loss in optical spectrum is compensated by high directivity beam scanning antennas. Assuming indoor use, a base station antenna at the ceiling center should illuminate coverage area uniformly by changing the beam width in orthogonal planes independently. This coverage area design is given by scanning a fan-shaped beam by high gain leaky wave antenna. We also present the design procedure based on the link budget in optical antenna system.
