Abstract
A wireless communication device transmits and receives a high-frequency signal having a first frequency as a carrier frequency. The device includes a base material made of paper, an antenna pattern of an Sn alloy formed on the base material, and an RFIC element connected electrically to the antenna pattern. Moreover, the antenna pattern including a thin wire part and a thick wire part that differ in wire width from each other.
Claims20
A wireless communication device for transmitting and receiving a high-frequency signal having a first frequency as a carrier frequency, comprising:
- a base material formed of paper;
- an antenna pattern of a Sn alloy and that is disposed on the base material;
- and
- an RFIC element connected electrically to the antenna pattern, wherein
- the antenna pattern includes a main antenna pattern of a meandering shape, and
- the main antenna pattern includes a first antenna pattern that extends in an amplitude direction of the meandering shape and a turning pattern where a direction of extension of the main antenna pattern is reversed, and
- the antenna pattern includes loop patterns, each including the first antenna pattern, the turning pattern, and an opening, with each of the loop patterns including a thin wire part and a thick wire part that each have a different wire width with respect to each other.
