Abstract
PURPOSE:To improve the degree of freedom of vehicle design while keeping the reception characteristic by constituting the titled system by an antenna comprising an antenna element provided under the vehicle and a reactance loading means fitted thereto and a shield means shielding the noise source of the vehicle or scattered substance. CONSTITUTION:The antenna system 9 consists of the antenna element 3 provided under the vehicle, the antenna consisting of a metallic plate 4 as a reactance loading means provided to its tip and a shield plate 5 connected to ground through a floor panel 6 among the antenna, engine auxiliary equipment and electric component or the like as a noise shield means implanted on the floor panel 6. The distribution of the electromagnetic field around the vehicle exists even under the vehicle and its strength is not inferior to that of the upper part of the vehicle, when the characteristic of the antenna system is made proper by the reactance loading means, the reception characteristic equal to the rod antenna provided above the vehicle is obtained and the scattered substance such as mud or noise generated from the vehicle is shielded by the shield plate 5.
