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.
