Method of mounting RF transponders on containers

摘要

A container 10 comprises a reflective contents 16 which, in use, reflects radio frequency energy. A transponder 22 of a radio frequency identification is mounted on the container. The identification system operates with an energizing signal having an operating wavelength . The transponder comprises an antenna 26 comprising a feed element 26.1. The feed element is spaced from reflective contents 16 by an electrical distance of at least /100. A dielectric medium 20 is located between the feed element and the reflective element, to space the feed element from the reflective contents. <IMAGE>
