The present application provides a handheld wireless communication device. The handheld wireless communication device includes a two part housing having an upper housing and a lower housing, the upper housing and the lower housing being rotatably coupled together via a hinge. The upper housing and the lower housing through a relative movement via the hinge can transition between an opened position and a closed position. The lower housing has a first conductor including one or more tuned structures and has a second conductor including one or more tuned structures, where each of the tuned structures of the first conductor and the second conductor are adapted for at least one of transmitting or receiving electromagnetic energy having a respective predefined range of frequencies in support of wireless communications. The first conductor and the second conductor in a spaced apart fashion relative to each other are located proximate a first side edge of the lower housing, where the first side edge is opposite a second side edge of the lower housing, where the second side edge of the lower housing is the side edge of the lower housing, which is most directly coupled to the upper housing via the hinge.

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.
