In this article, the authors describe a magnetic core for wireless power transmission in a mobile device, which includes a substrate, at least one microstrip line, and a magnet core.Abstract:
Disclosed is a resonator for wireless power transmission used in a mobile device. The resonator includes a substrate, at least one microstrip line, and a magnetic core. The microstrip line is formed on the substrate and is provided at one side thereof with a slit to have an open-loop shape. The magnetic core is formed on the substrate and is disposed on a space defined by the microstrip line to increase coupling strength.read more
