Abstract: A vehicle window mounted in vehicle having a split ground plane carries an antenna having a substantially larger horizontal dimension than vertical dimension. The antenna is arranged so that a plurality of parallel horizontal wire cross connecting elements constitute a major portion of the horizontal dimension in the horizontal plane and two parallel vertical wire spaced whip elements extend in the vertical dimension in the vertical plane. The parallel wire horizontal cross connecting elements function as delay lines and loading for adjusting the impedance of the antenna. The two parallel vertical wire spaced whip elements operate so that the vehicle body functions as a ground plane. The whip antennas in combination with the delay lines produce two directional pickup patterns at its two outputs ports.
