摘要： Implementations for heat structure for thermal mitigation are described. The described heat structures, for instance, provide a multi-layered structure that optimizes heat spreading and dissipation, as well as wireless performance of wireless devices. A heat structure, for instance, is installed internally in a wireless device adjacent various internal components to absorb heat generated by the components, and to dissipate the heat. According to various implementations, a heat structure is implemented as a thermally conductive layer surrounded by layers of electrically conductive material. Electrically conductive vias can be formed that traverse the thermally conductive layer and form an electrical connection between different electrically conductive layers to mitigate current flow in the thermally conductive layer.

摘要： An electronic communication device performs a method to detect proximity of an object to the device. The method includes determining a set of mutual coupling values for at least one pair of a plurality of antennas arrays of the electronic communication device. Each mutual coupling value indicates an efficiency of a mutual coupling transmission between an antenna element of a first antenna array of a pair of antenna arrays and an antenna element of a second antenna array of the pair of antenna arrays. The method further includes determining object position relative to the plurality of antenna arrays based on the set of mutual coupling values.

摘要： In aspects of managing antenna module heat and RF emissions, an antenna module includes antenna elements that emit radio frequency (RF) signals for wireless data communication. The antenna module also includes an integrated heat sink to dissipate heat generated by an amplifier on the antenna module, where the heat sink is formed as a metallic component having a surface approximately coplanar with the antenna elements. The antenna module also includes one or more grooves that are formed into the surface of the heat sink, where the one or more grooves are effective to allow the RF signals being emitted from the antenna elements without deformation of a radiation pattern of the RF signals.

摘要： A method and system for reconfiguring over-indexed antenna arrays in mobile devices are provided. For example, the method includes receiving sensor input that indicates an object blocking a first subset of reconfigurable antenna elements but not blocking a second subset of reconfigurable antenna elements of an over-indexed antenna array. The method also includes configuring, based on the sensor input, a number of the antenna elements in the first subset as non-active for radiating energy and a number of the antenna elements in the second subset as active for radiating energy.
