Abstract
A MIMO antenna device includes a front-side dipole antenna and a back-side dipole antenna. Long-side feed parts for hot element are connected respectively to feed points at their long sides. Long-side feed parts for ground element are connected respectively to the feed points at their long sides, and the long sides thereof face the long sides of the long-side feed parts for hot element in parallel with a predetermined interval. Ground elements are respectively arranged point-symmetric to hot elements with respect to the feed points in an offset manner. The front-side dipole antenna and the back-side dipole antenna are arranged such that the front-side feed point and the back-side feed point substantially overlap each other in a top view and that the long-side feed part for front-side is arranged perpendicular to the long-side feed part for back-side.
