摘要： The RFID system includes an RFID reader for sending information selected from among collision type information, idle type information, and readable type information, to all of the RFID tags depending on the number of signals in the corresponding time slot, and RFID tags for performing functions, in which, when information, indicating that a current time slot is a collision type, is fed back from the RFID reader, each of RFID tags selects one arbitrary value of either 0 or 1 and is assigned a time slot, in which a corresponding RFID tag will send a signal to the RFID reader, based on the selected value, a single tag group that caused a collision is divided into two sub-groups depending on the assigned time slots, and tags of the sub-groups send signals, including IDs thereof, to the RFID reader in different time slots for the respective sub-groups.

摘要： The present invention relates to a tag anti-collision Radio Frequency Identification (RFID) system and a method for tag identification. The method for tag identification consists of a first step of initializing a queue (Q) field and storing a prefix of a candidate queue (CQ) field in the queue field; a second step of transmitting a query including the prefix stored in the queue field to the RFID tags, and deleting the transmitted prefix from the queue field; a third step of inserting a prefix, in which prefixes 0 and 1 are inserted into a rear portion of a prefix of a previously transmitted query, into the queue field if two or more tags respond to the previously transmitted prefix and, therefore, the tags cannot be identified, and inserting the prefix of the previously transmitted query into the candidate queue field and deleting an unnecessary prefix stored in the candidate queue if there is no response or only one tag responds with respect to the previously transmitted prefix; and a fourth step of determining whether a prefix stored in the queue field exists, and returning to the second step if there is a prefix stored in the queue field.

摘要： An antenna structure for use in a communications device for reducing a user's SAR exposure. In addition to the conventional antenna elements, e.g., a radiating element and a ground plane, the antenna structure of the present invention comprises a conductive element for directing radio frequency energy emitted by the radiating element away from the user, thereby reducing the user's SAR exposure. The conductive element can be disposed on an interior or an exterior surface of a case enclosing the communications device.
