3D antenna for UHF RFID Tag On Molded interconnect device

An original design of 3D-MID antenna for passive UHF RFID tags is presented in this paper. For the first time the integration of RFID tag into the MID technology is considered. The novel tag based on a meander antenna and placed on the external face of a thermoplastic cylinder (LCP Vectra E820i) is compatible with Laser Direct Structuring (LDS) process. Both planar and 3D designs on MID substrate are discussed. In particular the influence of the 3D implementation on the RFID Tag performance is studied. Simulation results confirm the potential of this 3D design.
