摘要: Described herein are techniques related to near field coupling and wireless power transfers. A mobile device may include an edge-emitting antenna that offers ultra slim, all-metallic chassis packaging option with no cutout, uses lesser area, has robust mechanical strength, and provides EMI/ESD protection. In one example, an inductor coil is wrapped around a magnetic core and a pair of conductive layers is configured to interpose the magnetic core and the inductor coil between them to expose an edge of the magnetic core. The inductor coil being operable in a transmit mode to generate a magnetic field in response to a current passing through it. The edge is configured to enhance outward radiation of the magnetic field. Based on simulation results, the edge-emitting antenna occupies less space and provides an acceptable level of performance for coupling coefficients compared to conventional antenna.

摘要: Some embodiments include apparatuses and electrical models associated with the apparatus. One of the apparatuses includes an integrated circuit having a die; a package substrate; first conductive connections coupled between the die and a first side of the package substrate; second conductive connections located on a second side of the package substrate opposite from the first side. The second conductive connections are coupled to the first conductive connections through conductive paths in the package substrate. The first conductive connections and the conductive connections are associated with an S-parameter of an electrical model of the integrated circuit package. The electrical model further includes at least one of a current value associated with a power rail of the integrated circuit package, an impedance target associated with a location at the integrated circuit package, and a mapping associated with the first and second conductive connections.
