  • Patent number: 11055503
    Abstract: In a method for reading from an RFID-tagged article and an RFID system, information is accurately read from an RFID tag while interference with other devices is prevented by use of a compact and simple configuration. An article is conveyed on a conveyor belt. Also, an RFID tag is attached to the article. Information on the RFID tag is read by a leaky coaxial cable that is a stationary read/write antenna in a vicinity of the conveyor belt. The leaky coaxial cable is above the conveyor belt and at least a portion of the cable traverses the conveyor belt.

  • Patent number: 10992042
    Abstract: An antenna is connected to a first end of a high-frequency transmission line, and a connector is connected to a second end of the high-frequency transmission line. A characteristic impedance of a microstrip line is higher than characteristic impedances of first and second strip lines, and a characteristic impedance of a coplanar line is higher than a characteristic impedance of the second strip line. Thus, at a certain frequency, a standing wave develops in which the position of the microstrip line and the position of the coplanar line are maximum voltage points and three-quarter-wavelength resonance is a fundamental wave mode. Thus, the cutoff frequency of the high-frequency transmission line is high, and an insertion loss of a signal is significantly reduced to be low over a wide band.
