An antenna system for a vehicle radio integrated with the defogger heating elements in a window that provides enhanced impedance matching without requiring lumped matching components. The antenna system includes a vehicle window, a conductive grid embedded in the vehicle window and having a plurality of horizontal and generally parallel conductive elements, and first and second bus bars connecting the grid at opposite ends. The antenna system has first and second vertical conductive elements embedded in the vehicle window and arranged substantially orthogonal to the horizontal conductive elements. Tuning elements are coupled to each of the first and second vertical conductive elements and are substantially orthogonal thereto. The tuning elements have a length selected so as to substantially match characteristic impedance of an RF signal path. The horizontal heating elements are engaged for heating the vehicle window during a heating operation, and also serves to receive radio signals for the radio.
