Abstract
A first end of a first conductor pattern of a first coil conductor is connected to a power supply terminal, and a second end of the first conductor pattern is connected to an antenna terminal. A second conductor pattern includes second coil conductors. A first end of the second conductor pattern is connected to the antenna terminal and the second end of the first conductor pattern, and a second end of the second conductor pattern is connected to a ground terminal. The second conductor pattern magnetically couples with the first conductor pattern. The second end of the first conductor pattern and the first end of the second conductor pattern are connected to the antenna terminal via a routing pattern that extends to magnetically couple with at least either the first conductor pattern or the second conductor pattern.
