PROBLEM TO BE SOLVED: To easily perform operation accompanying installation of antenna to vehicles, and to eliminate degradation in receiving quality by a well-suited grounding connection. SOLUTION: A film antenna 2, 3 pasted up on the front glass 4 of a vehicle has a plurality of antenna elements 11, 12, 21, 22 formed on film substrates 10, 20. Amplifiers 16, 26 are arranged on pillars 6, 7 and grounding is given to a high-frequency component by high-frequency grounding members 17, 27 in a portion close to feeding points 15, 25 to the antenna elements 11, 12, 21, 22. The high-frequency grounding members 17, 27 can be mounted only by pasting up on a coated film and the like covering the exterior parts of a vehicle body, and no peeling operation and the like are required to coated films. Accordingly, easy operation can be expected accompanying the antenna installation to the vehicle. The grounding to a DC component is implemented through a DC earth 35 close to a selector 8 or a receiver 9 apart from the feeding points 15, 25. COPYRIGHT: (C)2008,JPO&INPIT
