摘要:
The present invention relates to an RFID parameter setting method and device in an RFID system including a first means for comparing a first mobile country code provided by the outside and a currently set second mobile country code, and generating a control signal for changing an RFID parameter setting of the RFID system according to the RFID standard that corresponds to the first mobile country code when the first mobile country code and the second mobile country code do not correspond with each other, and a second means for setting an operational frequency of the RFID system according to the control signal.

An RFID tag attached to an object and transmitting a signal that corresponds to identification information includes an RFID tag chip that modulates the signal according to the identification information and an RFID tag antenna that transmits the modulated signal. The RFID tag antenna includes a dielectric material, a radiating patch, and a slit. The dielectric material has a polyhedral shape and includes a first surface that contacts the object and a second surface that is parallel with the first surface, the radiating patch is formed on at least a part of the second surface and radiates electromagnetic to waves, and the slit is formed on at least a part of the radiating patch to expose the dielectric material.

The present invention relates to an antenna for an RFID tag chip. The antenna includes a dielectric material, a radiating patch that scatters a signal from the RFID tag chip for transmitting the scattered signal, and microstrip lines having a terminal for the RFID tag chip. Accordingly, a small antenna that can be attached to metal can be realized.

An antenna includes a polyhedral dielectric material, a feed loop, a polygonal radiating patch, and shorting plates. The feed loop is electrically connected with a radio frequency identification (RFID) tag chip for supplying power to the RFID tag chip. The polygonal radiating patch is magnetically coupled with the feed loop for radiating the electromagnetic waves. Each of the shorting plates disconnects the radiating patch and a ground surface and controls the magnetic coupling of the radiating patch and the feed loop. Accordingly, an RFID tag that can be attached to a metal material is provided.

An antenna attached to an object and transmitting electromagnetic waves that are modulated by an RFID tag chip includes a polygonal dielectric material layer that is adjacent to the object, a microstrip patch that determines a resonance frequency of the antenna, a microstrip line that is electromagnetically coupled with the microstrip match, and a shorting pin that disconnects the object and the microstrip line. Accordingly, a small-sized antenna that can be attached to metal can be realized.
摘要:
An RFID reader antenna including: a printed circuit board (PCB) formed as a dielectric substance; a plurality of slot groups, each having a plurality of slots, disposed on a first face of the PCB; a ground face disposed on areas, excluding the plurality of slot groups, of the first face of the PCB; and a feeder formed as a microstrip line with an open end on a second face of the PCB to feed the plurality of slot groups. Because the slots periodically formed on the ground face are fed in series by using the single microstrip line, the RFID reader antenna can reliably recognize a larger area with a simple structure. In particular, the RFID reader antenna can be useful for the bookstands for book management or smart shelves for displaying articles or goods including clothing goods in superstores or hypermarkets through the use of the ILT RFID application.
