Abstract:
1. A vehicular screen antenna comprising a dielectric sheet and a conductor extending on the sheet, a portion of the conductor being generally configured as a rectilinear loop with edges extending generally parallel to the edges of the sheet, the sheet being adapted to be fitted to a vehicle so as to extend generally vertically, the conductor also having a loop-entry segment and a loop-exit segment extending proximate each other on the sheet and being oriented on the sheet such that, after fitting of the sheet to the vehicle, the segments extend generally vertically and have first ends connected to proximate spaced positions on the loop and second ends positioned proximate a first edge of the sheet, the second end of the loop-entry segment being connectable to a signal feedline and the second end of the loop-exit segment being connectable to ground through reactive coupling; wherein the loop and segments are relatively sized such that, during operation of the antenna, a horizontally-polarized component of a linearly-polarized signal on the antenna has a magnitude at least approximating that of a vertically-polarized component of the signal.
