Abstract

PURPOSE:To improve the heat radiation efficiency without spoiling a function and a characteristic of an antenna panel by providing a fitting base having an air passing duct, an antenna panel supporting base, and a radome for covering the antenna panel, and also, allowing the transmission of a radio wave. CONSTITUTION:In an inlet of a duct side of a fitting base having an air passing duct 5 formed by a metallic material having high thermal conductivity, a fan 7 for executing air supply/exhaust of this duct 3 is provided. When the fan 7 is driven, a passage of cooling air is formed in the direction as indicated with an arrow 6 in the duct 3 provided on the fitting base 4. In such a state, heat generated in an antenna panel 1 is subjected to heat radiation by air passing through the duct 3. Also, a radome 5 covers the antenna panel 1 and is fastened to the fitting base 4, and the antenna panel l is protected from the outdoor environment. In this cases since the radome 5 allows a radio wave to transmit through, a function of the antenna panel 1 is not spoiled.
