An electronic device is provided. The electronic device includes a first conductive patch, a second conductive patch, a third conductive patch, and a wireless communication circuit. The first conductive patch includes a first edge facing the second conductive patch, a second edge perpendicularly meeting the first edge at a first corner, a third edge parallel to the first edge, and a fourth edge that is parallel to the second edge and perpendicularly meets the third edge at a second corner. The second conductive patch and the third conductive patch each have a shape identical to that of the first conductive patch. The wireless communication circuit feed power to a first point of the first edge, a second point of a fifth edge of the second conductive patch, and a third point of a sixth edge of the third conductive patch.
