Multi-loop antenna system and electronic apparatus having the same

An electronic apparatus comprising a housing, and an antenna module and a system module disposed in said housing;

• said antenna module including
• a substrate, and
• a plurality of loop antennas disposed on said substrate, and arranged such that each of extending lines extending respectively from geometric centers of said loop antennas to a center point that is bounded by said loop antennas has a predetermined length, and that each of said loop antennas is spaced apart from an adjacent one of said loop antennas by a predetermined minimum distance, each of said loop antennas including
• a first radiator portion operable in a first frequency band, and having opposite ends that respectively serve as a signal-feed section and a grounding section, and that are adjacent to and spaced apart from each other such that said first radiator portion substantially forms a loop, and
• a second radiator portion operable in a second frequency band, and having opposite ends that are connected electrically and respectively to said signal-feed section and said grounding section of said first radiator portion, such that said second radiator portion substantially forms a loop;
• said system module having a grounding plane that faces toward and that is spaced apart from and parallel to said substrate such that said grounding plane is able to reflect radiation from said antenna module.
