Abstract :
This paper presents the design of UHF RFID read/write (R/W) antenna to be used in a variety of smart shelf retail applications. The design principle based on the EM coupling between open-ended MS feed line and periodic planar metal strips is presented. The proposed antenna can be easily customized for the required aria of smart shelf RFID interrogation. Several antenna prototypes have been designed, produced and measured. The antenna performance has been evaluated in UHF RFID system for the simultaneous detection of arbitrary oriented tagged apparel items placed on the antenna surface. The proposed antenna demonstrates excellent ability to provide strong and uniform E-field distribution at the distances up to 50 cm form the antenna surface.
