Patent ID: 8330663

Claim:
An antenna for a vehicle which is formed on a space above defogging heater strips of a rear window glass of the vehicle, the antenna comprising: an AM broadcast wave receiving antenna including a plurality of horizontal strips provided at intervals, at least two vertical strips which are orthogonal to the horizontal strips, and which are apart from each other, and a first feed point provided between the two vertical strips, on uppermost one of the horizontal strips or through an extension line extending from a portion of the uppermost one of the horizontal strips; and an FM broadcast wave receiving antenna which extends in a clockwise direction or in a counterclockwise direction from a second feed point provided above the uppermost one of the horizontal strips of the AM broadcast wave receiving antenna, along a part of an outermost portion of the AM broadcast wave receiving antenna to surround the AM broadcast wave receiving antenna, and which is adjacent to at least a part of the horizontal strips of the AM broadcast wave receiving antenna to achieve a capacitive coupling, wherein the FM broadcast wave receiving antenna is an L-shaped or U-shaped element including a horizontal strip which extends in a horizontal direction from the second feed point, and which is adjacent to the horizontal strip of the AM broadcast wave receiving antenna to achieve the capacitive coupling, and a vertical strip extending in a substantially vertical direction or in an arc from an end of the horizontal strip of the FM broadcast wave receiving antenna, along outsides of the plurality of the horizontal strips of the AM broadcast wave receiving antenna, wherein the FM broadcast wave receiving antenna includes one or two return horizontal antenna which is formed by returning an end of the FM broadcast wave receiving antenna, and which is adjacent to the end of the horizontal strip of the AM broadcast wave receiving antenna to achieve the capacitive coupling, and wherein the FM broadcast wave receiving antenna wraps around ends of the plurality of the horizontal strips of the AM broadcast wave receiving antenna.
