Abstract: A multiple-input multiple-output (MIMO) antenna device for spatial multiplexing transmission and that includes: a front side dipole antenna arranged on a front side surface; and a rear side dipole antenna arranged on a rear side surface which faces the front side surface. The front side dipole antenna and the rear side dipole antenna have a same frequency band. The front side dipole antenna includes a front side bowtie antenna, and the rear side dipole antenna includes a rear side bowtie antenna. The front side bowtie antenna or the rear side bowtie antenna includes, at a side surface defined between the front side surface and the rear side surface of the MIMO antenna device, a side surface element portion for adjusting antenna performance which extends from the front side bowtie antenna or the rear side bowtie antenna.

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.

Abstract: A patch antenna includes a patch element and a ground conductor facing the patch element. The patch element is convex toward a side opposite to a side facing the ground conductor. Preferably, the patch element is convex while centering around at least one center line. Here, end portions on both sides of the patch element are positioned across the center line to face each other, and surfaces parallel to a direction toward the ground conductor from the respective end portions on the both sides at the shortest distance intersect or become a same surface.
