  • Patent number: 8717125
    Abstract: There is herein disclosed an interdigital capacitor, an inductor, and an LH transmission line and a coupler using the interdigital capacitor and the inductor. The interdigital capacitor comprises two finger sets which are substantially disposed in parallel with each other. Fingers of each finger set are overlapped at outer edges thereof with each other to thereby generate capacitance. The inductor is formed substantially spirally inside the transmission line, so that it can have a large inductance in a compact shape and can be used in a broad frequency band. The LH transmission line has a broad frequency band in a compact shape, which includes interdigital capacitors connected in series with each other and inductors connected in parallel with each other. In addition, the coupler employing the LH transmission line has an excellent couplability.

  • Patent number: 8350676
    Abstract: Provided are an RFID operating system and an RFID system operating method for allowing multiple RFID readers to read tags without collision. The RFID system operating method includes the steps of grouping RFID readers spaced apart by more than a spacing distance capable of avoiding collision between RFID readers into a single group to determine at least one group, classifying RPM readers included in each group into at least one sub-group based on a read time of each RFID reader, and driving the RFID readers such that RPM readers belonging to at least two different sub-groups that do not collide with each other simultaneously operate. According to the present invention, switching is performed sub-group by sub-group to reduce the number of switching operations and sub-groups can simultaneously operate to decrease a read time.
