Abstract
An antenna device includes: a pair of first elements that are arranged on a first plane; and a pair of second elements that are arranged on a second plane parallel to the first plane such that a polarized wave direction of the pair of second elements is orthogonal to that of the pair of first elements. Each element of the pair of first elements and the pair of second elements includes a portion that acts as a self-similarity antenna or an antenna that acts based on similar operating principle to the self-similarity antenna. In one embodiment, each element of the pair of first elements and the pair of second elements includes two arms that extend in a direction away from each other from a proximal end portion to which a feed point is connectable.
Claims9
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 in a state in which the pair of second elements are turned by a predetermined angle from a position at which a center portion of the second element is aligned with a center position of the first dipole antenna while maintaining a predetermined space.
