ABSTRACT:
In a wireless IC tag, metallic antennas are deposited as thin films on the front and back surfaces of a spacer, made of a heat-resistant glass epoxy material having a desired dielectric constant, to form a first antenna and a second antenna. An IC chip is mounted in the center of the first antenna. The second antenna functions as an auxiliary antenna for resonating to a desired frequency of a transmission radio wave of the first antenna to strengthen the intensity of the radio wave. Accordingly, even when the IC tag is mounted to a cable or the like, the tag can be mounted in the interior of the enclosure of the cable and thus the radio wave intensity of the first antenna can be prevented from being weakened by a metallic member in the cable.
