Abstract: This document describes an integrated cellular and ultra-wideband antenna system for a mobile electronic device. The cellular and ultra-wideband antenna are located in close proximity to one another, along with a circuit designed to enhance isolation between the two antennas. The circuit is also designed to enhance the efficiency of the cellular antenna by permitting the ultra-wideband antenna to generate an additional resonance in the cellular band. The integrated cellular antenna and ultra-wideband antenna results in reduced mutual coupling and performance degradation of the antennas, and the cellular antenna may gain enhanced bandwidth and efficiency.
