PROBLEM TO BE SOLVED: To provide a flat antenna device capable of shortening the length of an antenna aperture pitch depending on an arrangement space, while desired beam characteristics can be obtained. SOLUTION: In the flat antenna device, radiating element units each having a pair of radiating elements connected to both ends of a connection path are arranged in a matrix form to form a radiating element array, and the electric power of the same phase is supplied from a power supply unit in the center of the radiating element array to each radiating element through feeding lines. A part of the feeding lines is constructed of a feeding line comprising a curved section formed of a predetermined curvature. COPYRIGHT: (C)2004,JPO
