    Abstract: A HF-band wireless communication device includes a wireless IC configured to process a radio signal, a first substrate including a first inductor pattern coupled to the wireless IC, and a second substrate which includes a coil-shaped second inductor pattern coupled in series to the first inductor pattern. An L value of the first inductor pattern is greater than an L value of the second inductor pattern, and the L value of the first inductor pattern is dominant in a resonant frequency of a resonance circuit including the first and second inductor patterns. A winding diameter of the second inductor pattern is greater than a winding diameter of the first inductor pattern, and the second inductor pattern defines a main radiating element.
