Slot antenna having a slot portion formed in a vehicle mounted insulator

摘要

A conductor is mounted on the window glass of a vehicle in a manner that allows a slot portion between the conductor and the body. A space is allowed within the conductor, and a defogger is mounted within the space. The conductor and the body are fed. This arrangement constitutes a simple structured vehicular slot type antenna on the window glass. The area of the conductor may be reduced by taking advantage of the rear defogger as a conductor.
