Abstract

A UHF radio frequency identification tag antenna using an inductively coupled feeding method and meander lines is proposed. The antenna has a compact size (diameter: 0.08Ξ», 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. Β© 2009 Wiley Periodicals, Inc.

## Abstract A compact CPW‐fed UHF RFID tag antenna for metallic objects is proposed. It is less sensitive to the size of metallic objects and has a low profile and a long reading distance. The antenna consists of shorting walls, CPW feed line, a tag IC, and a radiating patch with Ishaped slits. The
