The present invention relates to a glass antenna suitable for receiving M radio broadcast waves and AM radio broadcast waves.

Description of the Related Art Conventionally, as a glass antenna for a vehicle, an antenna provided in an upper margin portion or a lower margin portion of a conductive wire for heating a rear window glass, and an antenna provided with a linear antenna in a front window glass. It is known and put to practical use, but in the former case, the space occupied by the antenna is reduced because the space is originally small and the view may be obstructed, so that sufficient reception gain cannot always be obtained.

Therefore, due to the widespread use of RVs equipped with side windows having relatively large areas and relatively few such windows, antennas provided on the side windows have attracted attention. 61509, JP-A-61-265
Numerous applications such as 904 have been filed.

い状況である。[0005] Especially in the case of RV vehicles, the rear window glass can be opened and closed in many cases, and even if the rear window glass does not open and close, the size of the rear window glass is small and the mounting angle is close to a right angle. The occupied area of the antenna in the upper margin or lower margin of the wire is small, and even if an antenna wire is provided in this location, sufficient reception gain cannot be obtained, and particularly AM radio broadcast waves and FM radio broadcasts having low reception frequencies. This is remarkable in the case of antenna strips for receiving waves. In recent years, antennas for radio broadcast reception provided on side window glasses have been demanded, but proposals have hardly been made. .

The antenna of the present invention has an S-shaped pattern in which one end of three horizontal lines provided on the upper side, the lower side, and the center is connected by a vertical line on one side.
Since the total length can be made longer than that of a pattern such as a character shape or a pattern that makes one round over the entire circumference, the reception gain can be further increased for FM radio broadcast waves, and the center can be further increased. By arranging horizontal stripes in the part, the effective reception area can be increased as compared with a pattern in which conductive stripes extend one or more rounds all around the periphery, so that AM radio broadcast waves can be suitably received. By forming a part or all of them in a double form, the receiving area of the antenna can be increased, so that the receiving gain for AM radio broadcast waves can be improved.

In the second and third embodiments, when the AM radio broadcast wave is received, the signal can be received independently. However, when the FM radio broadcast wave is received, the structure of the present invention provided on the other side window glass is used. It is preferable to perform diversity reception in combination with an FM radio broadcast wave receiving antenna or an FM radio broadcast wave receiving antenna having another configuration. Further, diversity reception may be performed in combination with a glass antenna provided on a rear window glass, a glass antenna provided on a front window glass, a whip antenna, or the like.
