Abstract:
A vehicular glass antenna is provided. The antenna includes an AM broadcast wave receiving antenna having a plurality of horizontal strips and at least two vertical strips with an AM feed point between the vertical strips on the uppermost horizontal strip or through a line extending from the uppermost horizontal strip, and two FM broadcast wave receiving antennas extending from two FM feed points provided above uppermost horizontal strip of the AM antenna along a part of an outermost portion of the AM broadcast wave receiving antenna. The FM antennas extend in opposite clockwise and counterclockwise directions. The FM antennas have a substantially U-shape surrounding the ends of the AM antenna horizontal strips on their respective sides, and include a second horizontal strip adjacent to the horizontal strips of the AM antenna to achieve capacitive coupling.
