ON-BOARD ANTENNA

摘要

PROBLEM TO BE SOLVED: To provide an on-board antenna for enhancing transmission/reception characteristics while suppressing deterioration in mounting property to a vehicle and reducing interference among antennas even when a plurality of the antennas are mounted on the vehicle. SOLUTION: The on-board antenna is configured by being provided with: a planar antenna using rear glass for a dielectric board and placed on the interior surface of the rear glass; and a pair of linear conductors 12, 12 located at a position apart from the planar antenna and provided on the interior surface of the rear glass in a way of sandwiching the planar antenna from both sides. A pair of the linear conductors 12, 12 formed longer than the width of radiation conductors 21 and placed at a position apart from the outer edge of a ground conductor 12 by a prescribed distance L in parallel with proper sides of a pair of two opposed sides of the radiation conductors 21.
