1. A MIMO antenna device for spatial multiplexing transmission, comprising:
a first dipole antenna including a pair of first elements connected to a first feeding point and arranged on a first plane, and
a second dipole antenna including a pair of second elements connected to a second feeding point and arranged on a second plane which is parallel to the first plane,
wherein, in the second dipole antenna, the second feeding point overlaps with the first feeding point when viewed from a plane, and
wherein the pair of second elements are arranged to face the pair of first elements in a state in which the pair of second elements are rotated by a predetermined angle from a position at which a second center portion of the second dipole antenna is aligned with a first center portion of the first dipole antenna while maintaining a predetermined space, thereby enabling a stable operation of the MIMO antenna device over a desired frequency band.
