RFID Tag Antenna Design on Curved Surface for Industrial Product

Abstract

This research presents a design and fabrication of UHF RFID tag antenna. The antenna design is based on microstrip and slot antenna. The antennas are designed for the metallic surface curve surface and non-metallic surface which are appropriated for automatic identification inventory management logistics management and industrial product with a variety of surface materials. The tag antennas are designed for NXP G2XL chip with the impedance of 15.873+j148.82 ohm considering at the center frequency with 922.5 MHz. The proposed antennas can operate covering the frequency band of 920-925 MHz along the UHF RFID Thailand standard. The simulated was done by the program using electromagnetic waveform analysis. The proposed antennas were measured to evaluate the performances. The proposed antennas can be operated on metallic surface curve surface and non-metallic surface.
