Abstract
A plate board type MIMO (multiple-input multiple-output) array antenna including a board, a plurality of antenna elements manufactured on the board, and an isolation unit offsetting effects of electromagnetic waves radiated from the plurality of antenna elements on the other antenna elements of the plurality of antenna elements. In a case where two antenna elements are used, the isolation unit may include at least one isolation element positioned within a space between the two antenna elements on the board and symmetric with respect to a center of a distance between the two antenna elements.
