ABSTRACT:
An FM signal antenna for window glass mounting in a motor vehicle includes an elongated conductor formed as a ladder to form a series of openings along its length. Preferably, the ladder is constructed of a pair of parallel conductors and crossmember conductor segments coupled across the parallel connector. The crossmember conductors are spaced from each other a distance substantially less than the wave length of the signals to be received. In addition, the antenna includes a raised feed point positioned along the length of the conductor. The conductor has a length substantially greater than the window area so that a fold is formed in the conductor, and an extended portion of the conductor overlapping from the fold is preferably aligned with the feed point. In addition, the antenna is mounted above a heater grid comprising a plurality of transverse conductors extending between common potential conductors at either end of the grid. Preferably, equipotential line conductors extend across intermediate portions of the grid, and an equipotential line conductor is aligned with the feed point of the FM antenna.
