<P>PROBLEM TO BE SOLVED: To reduce the size of a tag which can be stuck to a metal while keeping a practical communication distance, and to prevent the communication distance from being shortened when a plurality of the tags are used in close proximity to one another. <P>SOLUTION: A tag antenna is composed of a dielectric spacer, and an antenna pattern formed at one side of a spacer while having a size smaller than a half-wave length at an operating frequency in which a slit pattern adapted to a resistance component and a capacitive component of a chip to be mounted is formed. <P>COPYRIGHT: (C)2009,JPO&INPIT |
