  "abstract": "A tablet stand is disclosed which incorporates a near field antenna configuration which couples to a near field antenna in the back of a tablet and provides a near field antenna coupling region for near field communication at the front of the tablet. The stand may be completely passive and use conductive antenna elements and passive resonance matching circuit elements to provide efficient coupling. In another aspect a thin profile passive keyboard adapted for use with a near field enabled tablet is provided. In another aspect a mounting bracket or holder, embedded antenna, and passive keyboard combination is provided adapted for converting a tablet into a notebook type configuration.",

  "description_excerpt": "Tablet computers typically have a majority of surface area devoted to a touch screen of some type while having different form factors, screen sizes and boundary regions around the screen. At the same time multiple wireless communication capabilities are desired with related antennas incorporated into the tablet structure. One such communication capability of interest is near field communication for short range communication using inductive or magnetic coupling. Depending on the specific tablet design and near field antenna design it may be necessary or convenient to place the near field antenna at the back of the tablet. Due to the short range nature of near field communication and depending on the material employed in the tablet screen and specific antenna location, near field communication may require bringing the object to be communicated with to the back of the tablet adjacent the near field antenna. While this may be perfectly acceptable during normal handheld use it may become problematic when the tablet is placed in a stand. Also, communicating with devices adapted for front side use may be impossible.\n\nIn a first aspect the present invention provides a stand for a portable device having a near field communication capability and antenna. The stand comprises a first section having a device support surface adapted to receive a back portion of the portable device, the first section having a first portion of a passive near field communication antenna, a second section having a second portion of the passive near field communication antenna, and a third section connected to the first or second section.",
