Abstract
A wireless communication device is provided for transmitting and receiving a high-frequency signal having a first frequency for communication is disclosed. The device includes a loop pattern having a first electrode and a second electrode as both ends, an antenna pattern, a third electrode capacitively coupled to the first electrode, and a fourth electrode capacitively coupled to the second electrode. The device includes an RFIC having a capacitive impedance at a second frequency higher than the first frequency, and a first current path and a second current path connected in parallel with each other between the third electrode and the fourth electrode. The RFIC is included in the first current path and the second current path has an inductive impedance at a second frequency.
