Abstract
An aspect of the present invention is an antenna pattern used in a UHF-band RFID inlay. The antenna pattern includes a first element and a second element. The first element is formed to include a loop portion and an emission portion. The loop portion includes a pair of electric power supply portions. The emission portion is connected to the loop portion, and extends line-symmetrically from the loop portion. The emission portion operates as a dipole antenna to emit a radio wave whose half wavelength is a first length. The second element is formed apart from the first element. The second element operates as a dipole antenna by electromagnetic coupling with the first element to emit a radio wave whose half wavelength is a second length. The second length is different from the first length.
