Abstract
A wireless communication device is provided for transmitting and receiving a high frequency signal having a first frequency for communication. The wireless communication device includes a base material, an antenna pattern formed on the base material, and a loop-shaped conductor pattern. The loop-shaped conductor pattern is formed on the same surface of the base material on which the antenna pattern is formed and arranged on both sides of the antenna pattern along an extending direction of the antenna pattern. A physical perimeter of the conductor pattern is shorter than the physical total length of the antenna pattern.
