The antenna device includes: an array antenna including an antenna board on which a plurality of element antennas is mounted on one surface and an integrated circuit is mounted on an other surface; a power supply including a power supply board on which a power supply component is mounted; a base supporting the antenna board in such a manner that the integrated circuit is connected to one surface of base, supporting the power supply board in such a manner that the power supply component is connected to an other surface of base, and to the base heat generated by the integrated circuit and the power supply component connected to the base being transferred; a mount supporting the base, being fixed to a moving body, and to the mount heat being transferred from the base; a radome; and a skirt dissipating heat transferred from the mount.

Antenna device

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.

Antenna apparatus

A waterproof ventilator includes: an outer hollow body including: an internal space; a side with an outer opening adopted not to be covered with a water film at a lower portion thereof; and a bottom; and an inner hollow body including an internal space, at least a part of which is housed in the outer hollow body, and including: an outer surface disposed so as not to cause a water film to stay in a gap with an inner surface of the outer hollow body; an inner opening provided at a position not to be hit directly with water entering into the internal space of the outer hollow body through the outer opening and adopted not to be covered with a water film; an upper opening provided at an upper side than the inner opening and communicating with an exterior of the outer hollow body; and a bottom.
