Patent abstract
An antenna device is provided in which a common mode current does not flow in a coaxial cable. The coaxial cable is uprighted at the end of the base plate and bent toward the notched portion of the cover so that the connector reaches to the notched portion. A short-circuit stub structure is provided in such a manner that a part of the outer sheath of the coaxial cable is removed to expose the outer conductor and a ring-shaped metal terminal is crimped to the exposed outer conductor. The ring-shaped metal terminal is fixed by using a screw to an acceptance member made of a stainless steel provided on the base plate. The terminal is provided at the position within 0.25λ from the feeding point of the ground antenna element.
