Design of antennas for metal mountable radio-frequency identification tags is driven by a unique set of challenges: cheap, small, low-profile and conformal structures need to provide reliable operation when tags are mounted on conductive platforms of various shapes and sizes. During the past decade, tremendous amount of research has been dedicated to meet these stringent requirements. Currently, the tag read ranges of several meters are achieved with flexible label type tags. Moreover, a whole spectrum of tag size-performance ratios has been demonstrated through a variety of innovative antenna design approaches. This article reviews and summarizes the progress made in antennas for metal mountable tags and presents future prospects.
