Antenna system for a smart portable device using a continuous metal band

摘要

A method and portable device provide multi-band, multi-antenna signal communication in a portable device having wireless communication capability. A portable device comprises a single loop multi-feed (SLM) antenna system which includes a continuous conductive ring located along and adjacent to a first device periphery area. The SLM antenna system also comprises multiple communication feeds each respectively coupled to one of multiple transceivers and to the conductive ring. The SLM antenna system includes multiple ground connection points each of which is coupled to a ground plane. Each ground connection point is selectively positioned at a corresponding location on the continuous conductive ring in order to configure, within the SLM antenna system, multiple corresponding antenna elements. The SLM antenna system enables frequency tuning associated with a first antenna element to be performed independently of frequency tuning associated with a second antenna element and supports signal propagation via the multiple antennas using respective frequency bands.
