Leakage wave antenna and antenna system equipped with it
Document Type and Number:
Japanese Patent JP6345325
Kind Code:
B1
Abstract:
【課題】目的の動作周波数において、交差偏波およびサイドローブを抑制しつつ垂直面内指向性において高チルト角を実現可能な、ＣＲＬＨ伝送線路を用いた薄型の偏波共用漏れ波アンテナを提供する。【解決手段】漏れ波アンテナは、誘電体基板２と、誘電体基板２の下面に形成されたグランド面９と、誘電体基板の上面に形成されたグランド部５、６と、グランド部５、６に隣接して配置され、誘電体基板２の上面に形成された、グランド付きコプレーナ線路を用いたＣＲＬＨ線路であって、該ＣＲＬＨ線路を構成する直列キャパシタ３および並列インダクタ４が誘電体基板２の上面に形成されている、ＣＲＬＨ線路とを含んでなる。【選択図】図２
