GLASS ANTENNA FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To achieve high antenna sensitivity in a desired band although the area of the band is small.SOLUTION: The glass antenna for a vehicle is arranged in a window glass of a vehicle provided with a hot-side power feeding portion and an earth-side power feeding portion. The hot-side power feeding portion and the earth-side power feeding portion are respectively provided with a hot-side power feeding point and an earth-side power feeding point. Three directions of the hot-side power feeding portion are surrounded by the earth-side power feeding portion. To the hot-side power feeding portion is connected one end of a hot-side element and the hot-side element is extended toward a direction of separating from the hot-side power feeding portion. One end of the earth-side element is connected to the earth-side power feeding portion and arranged to surround the hot-side element. The hot-side element and the earth-side element are contacted closely to be capacitively coupled in part.
