Antenna device

An antenna device comprising:

• an array antenna including a plurality of element antennas, an integrated circuit to operate the plurality of element antennas, and an antenna board on which the plurality of element antennas is mounted on one surface and the integrated circuit is mounted on an other surface that is a surface opposite to the one surface;
• a power supply including a power supply component to supply power to the integrated circuit and a power supply board on which the power supply component is mounted;
• a base supporting the antenna board disposed on a side of one surface of the base in such a manner that the integrated circuit is connected to the one surface, supporting the power supply board disposed on a side of an other surface which is a surface of the base opposite to the one surface in such a manner that the power supply component is connected to the other surface, 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 in such a manner that the power supply board faces one surface of the mount, being fixed to a moving body on a side of an other surface which is a surface of the mount opposite to the one surface, and to the mount heat being transferred from the base;
• a radome to house the array antenna, the power supply, and the base, the radome being attached to the mount;
• and
• a skirt provided on an outer surface of the mount between the radome and the moving body, the skirt dissipating heat transferred from the mount.
