ABSTRACT:
A plurality of glass antennas formed as patterns on quarter glass panes are provided in opposite sides of a rearward portion of a vehicle body. Branching filters connected to feeding points of the glass antennas via coaxial cables, phase-shift circuits for phase adjustment of the FM band outputs separated by the branching filters, and combining circuits for combining the FM band outputs that have been phase-adjusted by the phase-shift circuits are contained in a shield case that is grounded to the vehicle body. The outer conductors of the coaxial cables at the branching filter side are grounded to the shield case therein.
