    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.

    摘要： Provided is a radio frequency identification (RFID) sensor tag antenna using an aperture coupling feeding method, including: a radiation patch for determining a resonance frequency of the RFID sensor tag antenna, which is disposed in an uppermost portion of the RFID sensor tag antenna; a first dielectric layer disposed on a bottom surface of the radiation patch and interposed between the radiation patch and a ground layer disposed to be parallel with the radiation patch; and a slot formed in a side of the ground layer and coupling RF signals to the RFID sensor tag antenna. Thus, the RFID sensor tag antenna can separately adjust resistance and reactance components of input impedance. As a result, the RFID sensor tag antenna can be matched with an RFID sensor tag board without an additional matching circuit.
