Abstract

　限られた空間しか有していないアンテナケースを備えるアンテナ装置にさらにアンテナを組み込んでも良好な電気的特性を得る。 　アンテナベース２０に立設されて取り付けられたアンテナ基板３０にアンテナ素子３１が形成されている。このアンテナ素子３１の直下に平面アンテナユニット３５が位置するようアンテナベース２０に固着されている。平面アンテナユニット３５の動作周波数帯の中心周波数の波長をλとした際に、平面アンテナユニット３５の上面とアンテナ素子３１の下端との間隔が約０．２５λ以上とされている。これにより、アンテナ素子３１の影響を受けることなく平面アンテナユニット３５の水平面内の放射指向特性を無指向性とすることができると共に、良好なゲイン特性が得られるようになる。
