Extension to Characterization Model for GPS Antenna Performance in Mobile Terminals

A new, extended model to evaluate the performance of Global Positioning System (GPS) antennas in mobile terminals is introduced. The new model is demonstrated using three different antennas with two orientations, and it is shown to give a more reliable prediction of the GPS antenna performance compared to the earlier model. Also, a new parameter for characterizing the ability of the GPS antenna to reject the reflected waves from the ground is introduced.
