<p><P>PROBLEM TO BE SOLVED: To provide a compact broadband antenna capable of suppressing degradation of a radiation efficiency at a desired wavelength band, and to provide an RFID tag. <P>SOLUTION: The antenna includes: a feeding part 11 constituted of a conductor; meandering parts 13a, 13b being a pair of meandered linear conductors connected to the feeding part 11 and extended to both sides of the feeding part 11 with the feeding part 11 as a center; and a pair of radiation parts 14a, 14b constituted of conductors and connected to respective outside end parts of the meandering parts 13a, 13b. The meandering parts 13a, 13b include a plurality of sides arranged in the longitudinal direction being a direction wherein the meandering parts 13a, 13b are extended, and a length in a direction perpendicular to the longitudinal direction of a part wherein ends of the radiation parts 14a, 14b at the side of the meandering parts 13a, 13b and a side closest to the radiation parts 14a, 14b among the sides of the meandering parts 13a, 13b are opposed to each other is made smaller than the widest part of the radiation parts 14a, 14b. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
