Abstract
The present invention is directed to achieving a favorable grounding state in a vehicle-mounted antenna. One end of a bent antenna elementis connected to an inner conductor of a coaxial cablevia a wiring conductor pattern of a substrate. An outer conductor of the coaxial cableis connected to a front grounding conductor pattern of the substrate. In the substrate, a plate capacitor is formed by the front grounding conductor pattern, a rear grounding conductor pattern, and a dielectric plate sandwiched between these grounding conductor patterns. The outer conductorof the coaxial cableis electrically connected to one end of a grounding bracketvia the plate capacitor. A tip portionof the grounding bracketis secured to a vehicle body by means of a boltand is electrically connected to the vehicle body.
