Patent attributes
An antenna apparatus is provided that allows cooling with a high heat dissipation effect even when the antenna apparatus is reduced in height. The antenna apparatus includes an antenna element, a mount on which the antenna element is provided, a radome to accommodate the antenna element, and a skirt provided on the mount. The mount on which the antenna element is provided has a side surface including a surface to which an inner circumferential surface of the radome is attached. A skirt provided on the mount has an outer circumferential surface on which a heat dissipation fin to dissipate heat to outside is formed. The heat is transmitted from the antenna element through the mount to the skirt.
