<P>PROBLEM TO BE SOLVED: To provide a glass antenna that allows for easy tuning of an antenna pattern so as to improve a composite value of antenna gains of two antenna conductors separated in a vehicle width direction of a vehicle in the antenna conductors disposed on a vehicle windowpane. <P>SOLUTION: A glass antenna constitutes a diversity antenna by an antenna conductor 21 and an antenna conductor 23 disposed separately in a vehicle width direction at an upper or lower part of a vehicle windowpane. The antenna conductor 21 and the antenna conductor 23 have antenna pattern shapes comprised of a filament element that are different from each other. Supposing a first rectangle externally contacting with the antenna conductor 21 and a second rectangle externally contacting with the antenna conductor 23, an area of the second rectangle is larger than an area of the first rectangle. <P>COPYRIGHT: (C)2013,JPO&INPIT |
