PROBLEM TO BE SOLVED: To provide an antenna device that flexibly implements desired directivity and diversity effect.SOLUTION: The antenna device includes: a substrate body 2; a ground plane GND formed on the substrate body; a pair of antenna occupancy areas OP1, OP2 arranged with a part of the ground plane in between; and a pair of antenna elements 3A, 3B disposed in the pair of antenna occupancy areas. The antenna elements extend at least partly on a base end side in directions perpendicular to edges of the ground plane in the vicinities of feeding points FP, and have the base end side connected with passive components P1a, P1b in the middle and a tip end side connected with antenna components AT1, AT2 extending in directions along the edges of the ground plane. The edges G1, G2 of the ground plane placed on the base end side of the pair of antenna elements are such that one extends in a different direction from the other and at least one inclines to an edge of the substrate body 2. |
