TLDR
In this paper, a power feed coil is disposed between the first conductor plane and the second conductor plane, where the coil conductor defines a pattern such that the coil conducts around the magnetic core and magnetically couples with the first connection conductor.Abstract:
An antenna device includes a first conductor plane and a second conductor plane that face each other. The first conductor plane and the second conductor plane are electrically continuous through a first connection conductor, a second connection conductor, and a chip capacitor. A power feed coil is disposed between the first conductor plane and the second conductor plane. The power feed coil includes a magnetic core and a coil conductor. The coil conductor defines a pattern such that the coil conductor winds around the magnetic core. The power feed coil is disposed at a position closer to the first connection conductor and magnetically couples with the first connection conductor.read more
