Abstract

A new wideband rectangular patch antenna for radio frequency identification tags mountable on metallic surfaces is presented. An orthogonally proximity‐coupled feed structure, in which the direction of the microstrip feedline is orthogonal to that of the resonant length of the radiating patch, is explored to perform simple and wideband impedance matching between an antenna and a tag chip without any additional matching networks. The proposed antenna has wideband characteristics and good cross‐polarization, which are validated by simulations and measurements. © 2007 Wiley Periodicals, Inc.

## Abstract The majority of commercial ultra high frequency radio frequency identification tags are based on the dipole antenna, whose performance degrades significantly when the tag is placed near a conducting surface. In this article, we present a radio frequency identification patch tag to opera
