An antenna (1) and an antenna (4) are disposed symmetrically with respect to a line of symmetry (103) on a grounded conductor (102). An antenna (2) and an antenna (3) are juxtaposed symmetrically with respect to the line of symmetry (103), such that a feeding point (24) and a feeding point (34) are separated by a prescribed distance. A radiation antenna element (13) and a radiation antenna element (43) are formed substantially parallel in the Y axis direction, and a radiation antenna element (23) and a radiation antenna element (33) are formed substantially parallel in the X axis direction. |
