Abstract: Techniques and apparatuses are described that implement collocated mm Wave and sub-6 GHz antennas. An apparatus includes at least one mmWave antenna that produces a near-field radiation region and a far-field radiation pattern in a mmWave frequency band. Disposed within the near-field radiation region is a sub-6 GHz antenna that produces a radiation pattern in a sub-6 GHz frequency band. The sub 6 GHz antenna is able to positively affect the far-field radiation pattern from the mm Wave antenna (e.g., via steering and/or broadening). In this way, the mmWave antenna and the sub-6 GHz antenna can be collocated to conserve space while also steering and/or broadening the far-field radiation pattern of the mm Wave antenna.

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.
