A user device includes an enclosure having an interior mounting surface for receiving one or more functional components. An antenna assembly has an electrical interface connectable to at least one of the one or more functional components. The antenna assembly includes a first half slot antenna angularly formed along both inner perimeter sides of a first corner of the enclosure.

User device having half slot antenna

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.

Geolocation antenna system

The present application provides a multiplex antenna matching circuit and method for coupling multiple signal ports to an antenna via cascaded diplexers. The multiplex antenna includes a diplexer for coupling a single merged port associated with an antenna with two separated signal nodes. The multiplex antenna further including at least one cascaded sub-diplexer. Each cascaded sub-diplexer is associated with a respective one of the two separated signal nodes, where the cascaded sub-diplexer further couples the respective one of the two separated signal nodes with a respective two further separated signal ports.
