Claims17
A portable media player, comprising:
- an antenna system, comprising:
- a dielectrically-loaded loop element;
- and
- a substantially planar element coupled with the dielectrically-loaded loop element, wherein the substantially planar element is disposed substantially parallel to a major axis of the dielectrically-loaded loop element, substantially perpendicular to a minor axis of the dielectrically-loaded loop element;
- a radio frequency (RF) transceiver coupled with the antenna system to transmit and receive media;
- a media processing system coupled with the RF transceiver to process the media;
- a storage device coupled to the media processing system to store the media;
- and
- one or more input-output devices to provide a user interface and to present the media to a user.
