An antenna (100) has an antenna layer (1), connective layers (2), and energizing circuit layers (10). The antenna layer (1) has horn antennae (51 to 53). The horn antennae (51 and 52) are disposed so that the mutual center is aligned in a direction (C). The horn antenna (53) is separated from the horn antenna (51) in a direction (D), and the centers of the horn antennae (51 and 53) are disposed so as to not be aligned in the direction (D). In the connective layers (2), a waveguide is formed. |
