摘要: The performance of flexible printed RFID tags affixed onto cylindrical containers is dependent on the inductive behavior bent antenna tag. Conductive polymeric coil antennas were screen substrates, and resistances, inductances, S-parameters coils measured analyzed. dies mounted read ranges characterized as a function curvature. results show that inductance decreased slowly with increasing curvature, maximum range was markedly reduced decrease in hypothesized to vary projected area instead geometric area. Experimental confirmed an tag curvilinear surface can be predicted by classical coupling model On basis experimental analytical results, reading reliability factor two proposed design parameter for tags.
