PROBLEM TO BE SOLVED: To provide an antenna device that can properly tilt the directivity of an antenna and improve the gain of the antenna.SOLUTION: An antenna has a dielectric substrate, a conductor plate disposed on one surface of the dielectric substrate, a first slot element formed in the conductor plate, a second slot element formed in the conductor plate substantially in parallel to the first slot, a slit, and a conductor disposed substantially in parallel to the conductor plate. The slit is formed in the conductor plate between the first slot element and a first end portion of the conductor located at the opposite side to the second slot element with respect to the first slot element. 【課題】アンテナの指向性を好適にチルトでき、アンテナの利得を改善できるアンテナ装置を提供する。【解決手段】アンテナ装置は、誘電体基板と、誘電体基板の一方の面に配置された導体板と、導体板に形成された第１スロット素子と、第１スロットと略平行に導体板に形成された第２スロット素子と、スリットと、導体板と略平行に配置された地導体と、を備える。スリットは、第１スロット素子と、第１スロット素子に対して第２スロット素子とは反対側に位置する導体板の第１の端部と、の間に、導体板に形成される。【選択図】図１
