Classification: CPC H  G | IPC G  H

Claim 0:
1. A wireless communication device for transmitting and receiving a signal having a first frequency for communication, the wireless communication device comprising:
a loop pattern;
a first electrode configured as a first end of the loop pattern;
a second electrode arranged at an interval from the first electrode and configured as a second end of the loop pattern;
an antenna pattern connected to the loop pattern;
a third electrode capacitively coupled to the first electrode;
a fourth electrode capacitively coupled to the second electrode;
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,
wherein the RFIC is included in the first current path, and the second current path has an inductive impedance at a second frequency.
