    摘要: An antenna device is disclosed. An antenna such as a dipole antenna and a parallel feeder each formed of a conductor pattern are disposed on a dielectric plate. The connector is connected to the antenna through the parallel feeder. The parallel feeder has a length of an integral multiple of a half wavelength and has an even number of bending points between the connector and the antenna.

    摘要: A wireless tag adapted for mounting inside a hollow electrically conductive pipe, includes: a contact placed in contact with the electrically conductive pipe so as to be electrically connected to the electrically conductive pipe; a lead wire placed inside the electrically conductive pipe along a longitudinal direction of the electrically conductive pipe and spaced a prescribed distance away from an inside wall of the electrically conductive pipe, thereby forming a coaxial line together with the electrically conductive pipe; and a wireless tag circuit, electrically connected at one end to the contact and at the other end to the lead wire, for generating a response signal in response to an interrogation signal transmitted from a reader/writer.

    摘要: A reader/writer 25 transmits an instruction for changing over between antennas 31 and 32, carried on a high frequency wave in the same format as a common command. A part of the antenna is equipped with a command interpretation circuit 30 which demodulates a high frequency wave received from the reader/writer body 25 and obtains a command content. If this command is an antenna changeover instruction of the reader/writer itself, the command interpretation circuit 30 instructs a changeover signal generation unit 28 for generating a changeover signal and changes over antennas by controlling a high frequency wave switch unit 29.
