PROBLEM TO BE SOLVED: To provide an antenna system capable of more decreasingly shifting a matching frequency without upsizing the antenna system. SOLUTION: In the antenna system (10) configured by forming a ground conductor (12) to the bottom face of a dielectric body (11) and continuously forming a radiation elements (13) to the entire ceiling face area and almost the entire area of side faces, at least one slit (13a) is formed on the radiation element formed on the side face on at least one side face, obliquely upward from the bottom edge of the radiation element.
