<p>One of the various embodiments of the present invention discloses an antenna device. The antenna device includes: a first radiating element and a second radiating element arranged to be spaced apart from each other; a first feed unit and a second feed unit respectively supplying power to the first radiating element and the second radiating element; a first feed port which connects the first radiating element to the first feed unit; and a second feed port connecting the second radiating element to the second feed unit. The first and second feed ports form an E-H coupling. The E-H coupling between the first and second feed ports has a phase difference from an E-H coupling established between the first and second radiating elements.</p>
