ABSTRACT:
An RF tag includes a first transmission line which is connected to a grounding conductor and forms an electric closed loop to constitute a dipole antenna. A power supply circuit is connected between a branch point on the first transmission line and the grounding conductor. A second transmission line is connected to the branch point and arranged in parallel with the power supply circuit to constitute an inductor.
