Abstract
An RF tag includes an RF tag antenna and an IC chip. The RF tag antenna is provided with: an insulation base material having a first main surface, a second main surface, and a first lateral surface; a first waveguide element provided on the first main surface; a second waveguide element provided to extend from the second main surface to the first lateral surface and the first main surface; and a power supply part and a short circuiting part that are provided on the first main surface. A planar inverted-F antenna is formed from the insulation base material, the first waveguide element, the second waveguide element, the power supply part, and the short circuiting part. The lengths of the power supply part and the short circuiting part are set such that the resonant frequency of an LC resonant circuit coincides with the reception frequency of radio waves.
