A glass antenna system with good rear visibility. A glass antenna has a first antenna conductor element extending on a blank region where no defogger hot wires extend, a second antenna conductor element which is capacitively coupled to the first antenna conductor element in a defogger region, a third antenna conductor element which extends at a position substantially symmetrical to the first antenna conductor element about the central line of the defogger, and a fourth antenna conductor element which extends at a position substantially symmetrical to the second antenna conductor element about the central line, and is capacitively coupled to the third antenna conductor element.
