Outline of Final Research Achievements

The heat-resistant gold plating and the gold nanoparticle generation on silicon wafers has been examined. The antenna operating in a wide frequency range of 320 GHz to 400 GHz has been prototyped. The 32x32-element antenna has achieved a realized gain of 38.0 dBi with an antenna efficiency of about 45%. A maximum of 32 Gbit/s has been obtained as the FEC limit at a distance of 40 cm in the OOK homodyne system. The sidelobe-suppressing structure have been demonstrated in the corporate-feed slot array antenna. The excitation for maximizing the transmission has been shown for a distance of 40 cm in the rectangular-coordinate two-dimensional orthogonal multiplexing system in the 60-GHz band.

Academic Significance and Societal Importance of the Research Achievements

今後の伝送容量の増加のためには，テラヘルツ帯において，シリコンプロセスを用いたアンテナの実現と多値変調伝送の実証に挑戦する必要がある。また，複数ビーム間の空間直交性を用いた多重伝送などのさらなる高機能化も重要である。チップ間等の無線通信応用の可能性を実証できた。高周波を利用することで，数十Gbit/s級の大容量データ伝送に必要な平面アンテナが実現でき，伝送実験による実証も行って，無線通信システムへの適用性を確認した。
