Abstract: The claimed subject matter includes techniques for performing power reduction for specific absorption rate (SAR) compliance. An example method includes receiving sensor inputs indicative of potential for non-compliance with SAR limits at a mobile device. The example method includes processing the sensor inputs to generate a SAR action table index. A look-up is performed in a SAR action table using the SAR action table index to obtain SAR data. The SAR data identifies SAR actions to be performed individually for each antenna of each wireless endpoint of the mobile computing device based on the plurality of sensor inputs. The SAR data may be sent to each of the wireless endpoints. Each of the wireless endpoints is to select an amount of power reduction to implement for each of the antennas associated with the wireless endpoint to maintain SAR compliance in response to the SAR data.

Abstract: The described technology includes an apparatus comprising a proximity sensor pad and booster element located between an antenna and the proximity sensor pad, wherein voltage level of the booster element at least ten percent higher than voltage level of the proximity sensor pad. Implementations of the booster element may be made of metal or metal-ink and may have U-shape or L-shape.

Abstract: Mobile device antennas with dielectric loading are described herein. In one example, a mobile device includes a ground plane, carried within an enclosure. An antenna is connected to the ground plane. Dielectric loading material is provided within at least a portion of an area defined between the ground plane and the antenna. The dielectric loading material results in a shortening of a required antenna length, thereby creating a recovered area, i.e., valuable space within the enclosure “recovered” by the use of dielectric loading material.

Abstract: Described is an antenna having a patch with slits configured to meet specified frequency and bandwidth requirements. For example, for a dual-polarized antenna with two feedlines, the patch has three slits that are configured to determine the antenna's frequency characteristics; the patch has no (or a substantially reduced) fourth slit, thereby providing wider bandwidth. The slits may be sized to provide the desired frequency characteristics. Also described is having the equivalent of variable slits via electronic or mechanical configuration. For diagonal feedlines, the slits may be symmetrically arranged, e.g., one horizontal slit extending from one side of the patch and two vertical slits extending from the upper and lower edges of the patch. The antenna may be used in a device such as a gaming console.
