PROBLEM TO BE SOLVED: To provide an on-vehicle antenna for facilitating works attended with installation of the antenna on a vehicle and preventing reception quality from being deteriorated through proper earth connection. SOLUTION: Film antennas 2, 3 adhered onto front glass 4 of the vehicle have antenna elements 11, 12; 21, 22 formed on film bases 10, 20. Amplifiers 16, 26 are located on pillar parts 6, 7, and high frequency grounding members 17, 27 ground high frequency components in the vicinity of feeding points 15, 25 to the antenna elements 11, 12; 21, 22. The high frequency grounding members 17, 27 can be mounted on the vehicle by having only to be stuck on coating film coated on the exterior of a vehicle body. Since no exfoliation work of film coating or the like is required, works attended with installation of the antenna on the vehicle can be facilitated. A DC component is grounded via a DC earth 35 in the vicinity of a selector 8 and a receiver 9. COPYRIGHT: (C)2004,JPO&NCIPI
