PROBLEM TO BE SOLVED: To make an antenna for a small-sized dielectric tag small in size. SOLUTION: Microstrip lines 12a, 12b, 12c, 12d, 12e, 12f and microstrip line discontinuous parts 13a, 13b, 13c, 13d, 13e are connected sequentially in the order of the line 12a, the part 13a, the line 12b, the part 13b,..., the line 12e, the part 13e, and the line 12f. An electromagnetic wave excited from a feeding point 15a reaches a tip of a transmission line of a 2nd layer connected by a through-hole 15c via an exciting conductor consisting of the microstrip lines and the microstrip line discontinuous parts. Thus, this configuration exhibits a characteristics of the antenna. |
