Metal mount RFID tag antenna excited by integrated loop/IC module
Résumé
A simple topology is described for radio frequency identification
(RFID) tags mountable on metal surfaces. The tag is built around a
commercial UHF RFID module combining an IC and a coupling
loop. The module is placed in the neighbourhood of a slot which is
used both to couple the energy from the module to the patch-like
antenna and to miniaturise the tag. A read range of almost 4 m is
obtained in the 865–868 MHz band with a 1.6 mm low-cost FR4
substrate.
