In this paper, a low-profile in-metal UHF RFID tag for identification of metallic components is described. The radiating element is printed on a 23×23×1 mm 3 copper-clad Alumina (Al 2 O 3 ) substrate (ε r =9, tanδ=0.0003) and consists of two rectangular Planar Inverted-F Antennas (PIFAs). A number of vias have been introduced to reduce the effect of the lateral metal walls when the tag is embedded in cavities created in metallic pieces. The entire structure has been optimized by taking into account the presence of a thin sheet of commercial epoxy resin used to protect the tag. Numerical results are here presented and discussed. Also, preliminary experimental results are shown in terms of reading range

Abstract
In this paper, a low-profile in-metal UHF RFID tag for identification of metallic components is described.

A number of vias have been introduced to reduce the effect of the lateral metal walls when the tag is embedded in cavities created in metallic pieces.
