| Outline of Research at the Start |
研究最終目標は円偏波用干渉除去アンテナ(Anti-Interference Antenna: AI-ANT)を創造することにある. 従来のAI-ANTは直線偏波用であり, 円偏波用AI-ANTの例はアンテナ構成が難しいために極めて少ない. この背景のもとに本研究では, AI-MetaANTとよばれる機能性の高い円偏波用アンテナを構築していく. アンテナの最終形態は, 円偏波放射メタマテリアルループを同心状に複数個配置したものとなる. アンテナ構築を通して, 学術上から干渉波除去についての電磁界特性を体系化する. 得られた成果は円偏波を使用する移動体間通信や, 衛星通信などに用いられる.

| Outline of Final Research Achievements |
With progress in communications systems, the deterioration in the communication efficiency, which is caused by interference of malicious electromagnetic waves, becomes a serious issue. Fortunately, this deterioration is overcome if an antenna acting as an input/output of the communication system is electromagnetically functionalized. Such an antenna is called Anti-interference Antenna: AI-ANT. It is noted that there are some AI-ANTs that radiate a linearly polarized wave, however there are few circularly polarized AI-ANTs due to difficulties in the antenna fabrication. The purpose of this project is to overcome the fabrication difficulties and create a circularly polarized AI-ANT. It is emphasized that this antenna is made of metamaterial atoms and has a thin plane structure. The antenna is abbreviated as AI-MetaANT.
