摘要： A near-field radio frequency identification (RFID) reader antenna is provided. The near-field RFID reader antenna is intended to separately recognize adjacent items to which a plurality of small RFID tags are attached, such as wines displayed on a shelf in a store or chip trays on casino tables, using a near field. The near-field REID reader antenna includes a dielectric layer, at least one signal line formed on the dielectric layer, a ground surface formed under the dielectric layer, at least one ground line formed under the dielectric layer to be electrically connected to the ground surface in parallel with the signal line, at least one signal stub formed to be electrically connected to the signal line toward the ground line, and at least one ground stub formed to be electrically connected to the ground line toward the signal line in parallel with the signal stub.
