ABSTRACT:
An antenna for an RFID tag includes each power feeding parts11that is formed of a conductor, meandering parts13aand13bthat are formed of conductors shaped as a pair of meandering lines, connected to the power feeding parts11, and extend from the power feeding parts11toward both ends of the power feeding parts11, respectively, a pair of radiating parts14aand14bthat are formed of conductors and connected to outer ends of the pair of meandering parts13aand13b, respectively. The meandering parts13aand13binclude a plurality of sides arranged in a longitudinal direction where the meandering parts13aand13bextend. Further, the lengths of portions, where the ends of the radiating parts14aand14bfacing the meandering parts13aand13bface the sides closest to the radiating parts14aand14bamong the plurality of sides of the meandering parts13aand13bin a direction orthogonal to the longitudinal direction, are smaller than the widths of the widest portions of the radiating parts.
