PURPOSE:To eliminate a high frequency loss caused by a cable and to eliminate necessity for the separate construction of an antenna by fitting the antenna by using a metallic enclosure housing a booster. CONSTITUTION:A conductor 18 is formed on a dielectric layer 17 attached to one face of a metallic enclosure 12 and a microstrip antenna is constituted with the upper surface of the metallic enclosure 12 as a base board. Since the enclosure becomes the base ground, the normal antenna can be used and since the number of wiring is reduced as well, the antenna can be fitted to the internal part of a vehicle. |
