ABSTRACT:
A first antenna conductor is provided onto a margin area of a group of defogging heater wires on a surface of a laminated window glass. A second antenna conductor is provided into an intermediate layer of the laminated glass. The former is tuned to receive waves in lower reception band and the latter is assigned to higher reception band with its conductor arranged to cross the heater wires. The first and second antenna conductors are coupled to obtain a good bandwidth characteristic even in relatively narrow space for conductors.
