    摘要: 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.

    摘要: 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.
