Abstract

A low-cost, wideband, flexible antenna for radio frequency identification tags mountable on curved metal surfaces is presented. The antenna consists of a label-type patch adhering to a flexible polyvinyl chloride substrate. A novel balanced feed method using two orthogonal slits on the patch is proposed to perform simple and wideband impedance matching between the antenna and a tag chip. A prototype antenna was fabricated and tested with a commercial tag chip. It has a 3dB return loss bandwidth of 70MHz and a uniform read range of over 9.7m in the 902-928MHz range when it is mounted on a cylindrical metal plate with a radius of curvature of 150mm.
