Abstract

AbstractA UHF radio frequency identification tag antenna using an inductively coupled feeding method and meander lines is proposed. The antenna has a compact size (diameter: 0.08λ, 26.4 mm), wide bandwidth, and simple matching technique between a tag antenna and a tag chip. To get a physical operation of the proposed antenna, a simplified structure is presented and analyzed. An equivalent circuit model with a simplified structure has good results compared with a simulation. © 2009 Wiley Periodicals, Inc.
