Abstract
Abstract A glass sheet with broad band receiver antennae and an area to be heated, comprising a glass sheet, a first means provided in the heating area of the glass sheet and capable of functioning both as a heating conductor wire and as a first receiver antennae for receiving waves in predetermined frequency band, an electric source connected to the first means for supplying a heating current to the first means, and a second means provided in an area of the glass sheet other than the heating area and capable of functioning as second receiver antennae for receiving waves in a frequency band different from the frequency band for the first receiver antennae. This glass sheet further includes a stub one end of which is connected to the first means and the other of which to the second means, and a feeder connected to the second means.
