    Abstract: An antenna for radio frequency identification tag is provided to allow matching to RFID tag chip efficiently by controlling impedance. A dielectric layer has the polyhedral shape while including a first side, a second surface, and a third side connected with the first side and the second side. A patch radiates the electromagnetic wave having concave polygonal shape. A feed Line(150) is adjacent to the third side of two sides where the meandering shape is formed. The both sides of the feed Line is connected with a radiation patch, and the feed Line supplies power to the RFID tag chip through magnetic junction.

    Abstract: PURPOSE: A master RFID tag for the administration of physical distribution and a method thereof are provided to enable users to confirm the robbery of products in the middle of circulation steps. CONSTITUTION: A tag reader unit(300) reads information of RFID(Radio Frequency Identification) tag attached to each product stored in a deposit box. A tag information storage unit(310) store the RFID tag information read by the RFID tag. A control unit(330) wirelessly transmits the RFID tag information stored in the tag storage unit to an external RFID reader unit. The tag reader unit is activated by an activation command. The control unit compares the read RFID tag information with the stored RFID tag information.

    Abstract: A synchronization method between a reader and a tag are provided to accurately perform the synchronization between a reader and a tag based on the calculation of both clock offset and message delay between the reader and the tag. A reader transmits a first write instruction message to a tag at first time(111), and the tag detects the first write instruction message from the reader at a second time. The tag transmits a first response message corresponding to the first write instruction message to the reader(112), and the reader the second write instruction message including time information for the first time to the tag(113). The tag corrects clock offset by using the difference between the first and second times.
