Abstract

There is provided receiving equipment for vehicles, being less susceptible to electromagnetic noise and having a preferable directivity. The receiving equipment (1) for vehicles receives, for example, an ultra-short-wave broadcast (FM broadcast). An antenna element (11) is disposed on the periphery of a metal roof portion (21) of a vehicle (20). One end of a radial (12) is electrically connected so as to become a voltage level equal to that at the position where the antenna element (11) on the roof portion (21) is disposed. The radial (12) also extends along the outer or inner surface of a rear glass (30) from the vicinity of the position where the one end of the radial (12) is connected to the roof portion.
