<p>An antenna system, comprising a left-hand circular polarized antenna, is disclosed for use in receiving signals from a GPS location satellite which are originally-transmitted as RHCP signals. Reception occurs after the right-hand circular polarized signal is reflected, or bounces off of, a surface one or more times. The number of reflections must be an odd number. The left-hand circular polarized antenna may be mounted underneath a vehicle or a building overhang. The method of the invention comprises the steps of transmitting a right-hand circular polarized signal and receiving the signal using a left-hand circular polarized antenna placed in a location where the right-hand circular polarized signal must be reflected by an odd number of surfaces before reception.</p> |
