<P>PROBLEM TO BE SOLVED: To sufficiently obtain effects by a booster antenna in an RF-ID medium using the booster antenna. <P>SOLUTION: Each of two antenna parts 22a and 22b constituting an inlet antenna 22 has a vortex shape by connecting the outer circumferential terminal portion thereof to an IC chip 21 and opening the inner circumferential terminal portion thereof while being wound oppositely to each other. When an inlet 20 is mounted on a paper substrate 11 in which a booster antenna 12 is formed, in the booster antenna 12, a current flows in an opposite direction in the vortex shape of the two antenna parts 22a and 22b in an area along the outer circumferential portions of each of the antenna parts 22a and 22b. <P>COPYRIGHT: (C)2012,JPO&INPIT |
