PURPOSE: An RFID reader antenna and an RFID shelf with the same are provided to serially supply power to slots which are periodically formed on a ground surface, thereby stably recognizing a large area with a simple structure. CONSTITUTION: An RFID reader antenna and an RFID shelf with the RFID reader antenna comprise a printed circuit board(210), a plurality of slot groups(220), a ground surface(230), and an RFID reader antenna(200). The printed circuit board is formed of dielectric materials. The slot groups are arranged on the first surface of the printed circuit board. The ground surface is arranged on the area of the first surface except the slot groups. A power supply line is formed on the second surface of the printed circuit board by a micro strip line. |
