Abstract
Disclosed is a radio wave marker reception antenna which is not easily affected by disturbance noises, such as a broadcast wave, which are set to the same frequency band as the radio wave signal conveying driving assisting information. The radio wave marker reception antenna is equipped with a cover which is formed of a conductive material and which has a prism-like, cylindrical, conical, dome-shaped, or forwardly broadening configuration. The cover may be installed such that it is inclined from the position where its lower side is oriented vertically downward to a position where its lower side is directed obliquely forward. Further, the interior of the cover may be filled with a non-conductive material.
