摘要： 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 RFID 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 RFID 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.

摘要： A single-layer dual-band antenna with circular polarization is disclosed. The antenna includes a first radiator formed on the top surface of a substrate and electrically coupled to a feeding element, and a second radiator formed on the top surface of the substrate, spaced apart from the first radiator by a predetermined distance and electromagnetically coupled with the first radiator. The antenna is thin because it has a single-layer structure. Furthermore, there is no deterioration in the radiation characteristic due to interference between the radiators. Moreover, impedances of the radiators can be independently matched at their frequency bands by adjusting the position of a feed point and the relative position of the radiators.

摘要： Disclosed is an antenna having an antenna radiator formed by printing electrically conductive ink on a substrate. An antenna radiator according to an embodiment of the present invention is formed to the same thickness as a skin depth with respect to an operation frequency of the antenna. Therefore, an antenna can be fabricated using a small amount of electrically conductive ink while not reducing the gain of the antenna. Further, an antenna radiator according to another embodiment of the present invention is formed to the same thickness as a skin depth with respect to a predetermined frequency at a corresponding hot spot with respect to the frequency. Accordingly, an amount of electrically conductive ink used can be further reduced while maintaining the gain of the antenna.
