Mobile device multi-antenna system
Systems for improving radio reception on a mobile device are provided. In exemplary embodiments, the system comprises a headset apparatus having a plurality of antenna elements. In exemplary embodiments, the plurality of antenna elements may be positioned in such a manner as to result in low-correlation between the plurality of antenna elements. For example, at least one of the antenna elements may be vertically oriented near a plug of the headset apparatus. Further antenna elements may be oriented vertically, horizontally, or both near an earpiece of the headset apparatus or above a juncture where a left and right cord of the headset apparatus splits. Exemplary embodiments may also comprise a receiving device configured to receive RF signals from the plurality of antenna elements and process these signals for playback on the headset apparatus.
