Abstract
Systems and methods for improved Global Positioning System ('GPS') function employ two multiband, multiport antennas to receive GPS signals. The antennas also serve WiFi frequencies, and the system utilizes the received WiFi signal strength to correct the GPS reception pattern for detuning due to user contact or other factors. The correction is made via selective combination of the GPS signals from the antennas. In addition, a phase shifter in one of the signal paths is used to account for changes in device orientation and to maximize the upper hemisphere component of the GPS reception pattern.
