Description
移動通信基地局エントランス回線として22GHz帯の無線方式が考えられている。これに用いるアンテナとして、共振スロットを用いた一層構造導波管スロットアレーを提案した。本報告では、その設計方法を示し、実験によりアンテナの実現可能性の確認を行った。導波管アレー用放射素子として従来より用いられている、共振スロットを用い、π分岐を用いた一層構造電力分配器により、構造の簡素化を図った。試作の結果、ビームチルトにより反射特性の優れたアンテナを構成することができ、57.1%という良好な開口効率が得られた。
22GHz band radio systems will be used to connect increasing number of base stations in mobile communication.We proposed a slotted waveguide array using resonant slots for that use.The design and feasibility of this antenna is discussed in this paper. The design of resonant slots has already been intensively studied; full wave analysis of the array is conducted.As a result of the experiments,fine reflection characteristics are obtained by using beam tilting technique and aperture efficiency of 57.1% is confirmed from gain experiment.
