Abstract
The present invention relates to relates to a multi-input and multi-output antenna apparatus, and particularly, to a multi-input and multi-output antenna apparatus including a main board having an accommodation space formed in at least one region and provided in the form of a predetermined space, and a sub-board stacked on a rear surface portion of the main board and configured such that a plurality of heating elements is mounted on a front surface portion of the sub-board that is directed toward the accommodation space, in which heat generated from the heating elements is dissipated to a rear surface portion of the sub-board, which makes it possible to improve heat dissipation performance of the antenna apparatus and improve frequency filtering performance of the antenna apparatus.
