Summary:To achieve an array antenna capable of securing excellent antenna characteristics even when a plurality of antenna elements are arranged at high density on a dielectric substrate.SOLUTION: An array antenna 1 using a dielectric substrate 10 is configured to include a plurality of antenna elements 20 and 30 arranged along a Y direction of the dielectric substrate 10 and one or a plurality of slit units 40 formed by partially cutting out the dielectric substrate 10. Each slit unit 40 constitutes an air layer for separating the antenna elements 20 and 30 adjacent in the Y direction.SELECTED DRAWING: Figure 1 【課題】誘電体基板に複数のアンテナ素子を高い密度で配置する場合であっても良好なアンテナ特性を確保し得るアレイアンテナを実現する。【解決手段】誘電体基板１０を用いたアレイアンテナ１は、誘電体基板１０のＹ方向に沿って配列される複数のアンテナ素子２０、３０と、誘電体基板１０を部分的に切り欠いて形成された１又は複数のスリット部４０とを備えて構成され、それぞれのスリット部４０はＹ方向に隣接するアンテナ素子２０、３０の間を隔てる空気層を構成している。【選択図】図１
