| Outline of Final Research Achievements |
A two-dimensional Rotman-lens multi-beam array-antenna was developed by using five-layer substrates of fluoro-carbon resin film with 1 mm thickness. Following three techniques are developed; (1) a two-dimensional Rotman-lens in which an H-plane Rotman-lens for power distribution for each layer and an E-plane Rotman-lens for power distribution in the layer direction, (2) a transmission-line transitions from a hollow waveguide on the back to a substrate integrated waveguide in each layer, (3) a radiating slot element that radiates from each layer of the multilayer substrate integrated waveguide.
It was confirmed both by electromagnetic simulation and experiment that 9 multi-beams can be generated with 3 beams each with a pitch of about 25 degrees on the horizontal plane and a pitch of about 12 degrees on the vertical plane.

| Academic Significance and Societal Importance of the Research Achievements |
今後、周波数の活用が期待されるミリ波帯において、波長が短いミリ波の特徴である小型のアンテナでも鋭い指向性ができる特性を活かし、高利得を広範囲にカバーする指向性走査技術を開発した。多層基板技術を用いることにより、これまでに困難であった、低コストが期待できるプリント基板技術で２次元ビーム走査技術の開発である。指向性走査技術はミリ波帯において、ミリ波レーダや在宅医療などの電波センシングや、５Gなどの通信応用に期待される技術である。
