Abstract:
1. An IC tag-bearing printed circuit wiring board comprising: a radio IC (integrated circuit) tag and an antenna coupled to the IC tag, the IC tag having stored thereon information to be transmitted, the antenna serving to radiate radio waves representative of the stored information to be transmitted, the antenna being disposed on the surface of an edge of the printed circuit wiring board, the edge connecting a first major surface of the printed circuit wiring board and a second major surface of the printed circuit wiring board; wherein the antenna is a dipole antenna having a length equal to about one half the nominal wavelength of the radio waves to be radiated; wherein the first major surface is a printed circuit surface; and an auxiliary antenna disposed on the first major surface or the second major surface, the auxiliary antenna having a long side oriented substantially parallel to the length of the dipole antenna, wherein the long side of the auxiliary antenna is longer than the length of the dipole antenna.
