1. A radio communication device comprising:
- a flat radiation element including a loop with a first end and a second end;
a feed element including a first coil pattern connected to the first end of the loop; and
a radio IC element connected to the first coil pattern;
whereinthe first coil pattern is disposed adjacent to the loop and is wound such that an electric power supply to the first coil pattern generates a current flow in the first coil pattern and a current flow in the loop in a same direction; and
the coil pattern and the loop are connected in series and are coupled via a magnetic field.

Abstract
A radio communication device includes a flat radiation element including a loop with a first end and a second end; a feed element including a coil pattern connected to the first end of the loop; and a radio IC element connected to the coil pattern. The coil pattern is disposed near the loop and is wound such that an electric power supply to the coil pattern generates a current flow in the coil pattern and a current flow in the loop in a same direction. The coil pattern and the loop are connected in series and are coupled via a magnetic field.
