Outline of Research at the Start

Internet of Thingsの推進により無線利用機器の数が増大し続けており,アンテナの電波放射性能を高速かつ視覚的に評価できる測定技術が求められている.本研究はアンテナ近傍界の振幅分布を用いた位相推定手法に関する研究成果をベースに,疎なアンテナ近傍界分布を用いて密なアンテナ近傍界の振幅と位相それぞれを独立な補間アプローチによって推定する,高速な平面状近傍界測定によるアンテナ放射特性の推定手法の確立を目的とする.また,提案手法に対して実際の測定で混入し得る外乱をシミュレーション上で混入させ,提案手法の外乱耐性を明確化する.

Outline of Final Research Achievements

In this study, we developed a method for estimating dense amplitude and phase distributions from sparse amplitude distribution in planar measurement domain near an electromagnetic sources. This method enables the fast measurement of radiation characteristics of high-gain antennas in the terahertz band, which are expected to be used in future wireless communications. We propose a method to estimate dense complex near-field distributions using sparse amplitude distributions on multiple planes. This method was applied to near-field distributions obtained through electromagnetic field analysis, demonstrating its effectiveness. Furthermore, by applying this method to the measured electric field distribution in the terahertz band, we verified the validity of the proposed method.

Academic Significance and Societal Importance of the Research Achievements

将来の無線通信ではミリ波・テラヘルツ波帯の開拓が強く推進されており,指向性を鋭く絞った利得の高いアンテナの利用が有望である.高利得アンテナの指向性測定手法として平面状近傍界測定が有効であるが,波源の近傍電界分布のサンプリングピッチを半波長未満としなくてはならず,長大な測定時間が問題であった.この課題に対して本研究では,数値処理に基づいて疎な電磁界分布から密な電磁界分布を推定することで実測定に必要な時間を削減できる.本手法によってテラヘルツ帯を中心とした,高利得アンテナの放射特性高速測定法を提供する.
