Abstract

近年,携帯端末の小形化に伴いアンテナの小形化が強く要求されている.これまで,携帯端末用内蔵型アンテナとして代表的な平板逆Fアンテナ(Planar Inverted-F Antenna,以下PIFA)に磁性体を装荷した小形化について報告されている.また,小形化に有効な磁性体形状を求めるためにトポロジー最適化手法(Topology Optimization Method,以下TOM)が新たに提案され,その妥当性が確認されている.ここではTOMにより得られた磁性体形状を実験によって確認すると共に磁性体量を考慮したPIFAの小形化について実験による検証を行いながら検討する.

With the recent rapid progress in handsets, the downsizing of their antennas is acquiring great importance. We have investigated a downsizing technique of antennas for handsets by utilizing magnetic materials. A planar inverted-F antenna (PIFA), which is one of the conventional antennas for handset, is used here. We used the Topology Optimization to find the effective material distribution and confirmed its validity as compared with the results calculated by other simulator. In this study, we make an experimental study about the effective material distribution obtained by the Topology Optimization in consideration of the volume of the magnetic materials.
