<p><P>PROBLEM TO BE SOLVED: To provide an earmark RFID tag for animals, reducing the influence by a living body such as the ear or the face of an animal of a managed object, and the interference of antennas to each other even when two RFID tags of dipole antennas are used as the antenna element. <P>SOLUTION: The earmark RFID tag for animals includes a tag part having a hole part, the first dipole antenna which is installed in the tag part and in which the first IC chip is electrically connected to the first power-supplying part through the first matching line, and the second dipole antenna which is installed in the tag part so that the second power-supplying part may face to the first power-supplying part, and in which the second IC chip is electrically connected to the second power-supplying part through the second matching line. The first angle that the direction directed from the hole part to the first power-supplying part makes with the slope of the first dipole antenna, and the second angle that the direction directed from the hole part to the second power-supplying part makes with the slope of the second dipole antenna are regulated so as to be different. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
