Abstract
An RFID tag includes an IC chip on which identification information is recorded, a loop-like conductor that is connected to the IC chip, and an antenna unit that includes two lattice-shaped antenna patterns connected to the loop-like conductor and extending away from each other from the loop-like conductor.
Claims9
An RFID tag comprising:
- an IC chip on which identification information is recorded;
- a loop-like conductor that is connected to the IC chip;
- and
- an antenna unit that includes a first lattice-shaped antenna pattern and a second lattice-shaped antenna pattern, the first lattice-shaped antenna pattern and the second lattice-shaped antenna pattern connected to the loop-like conductor and extending away from each other from the loop-like conductor, the first lattice-shaped antenna pattern formed by a first antenna conductor having a first closed loop, and the second lattice-shaped antenna pattern formed by a second antenna conductor having a second closed loop, wherein
- each of the first antenna conductor and the second antenna conductor includes a linear element which has a connection connected to the loop-like conductor, an angled portion extending from the connection at a predetermined angle with respect to a longitudinal direction of the RFID tag, and an extending portion extending in the longitudinal direction to be away from the loop-like conductor, the linear elements mutually extending so as to be separated.
