Document Type and Number:
Japanese Patent JP6762006
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To expand an information amount to be handled, attain use in a wide frequency band, and enable easiness of writing information into a tag, in an application to a chipless RFID.SOLUTION: A resonator 120 applied to a chipless RFID includes a first transmission line 121, a second transmission line 122 connected to one end 121a of the first transmission line, and a third transmission line 123 connected to the other end 121a on an opposite side of one end 121b of the second transmission line connected to the first transmission line. Among the first transmission line, the second transmission line, and the third transmission line, characteristic impedance of the second transmission line is largest, and line electric lengths of the first transmission line and the third transmission line are identical to each other.SELECTED DRAWING: Figure 4
