HFE-Lab

High Frequency Electronics (HFE) Lab, was founded in 2001 by inheriting ten years of experience in the area of modeling and design of microwave electronic circuits. This experience has been further exploited and finalized to several technological and scientifc challenges. Among them it is worth mentioning those running at present:

APMC-2012


Today at the Asia Pacific Micowave Conference (APMC) 2012, Luca Roselli gave the presentation:

"Heterogeneous Integration of Flexible Substrate Spiral Antennas and Silicon Chips by Magnetic Coupling"
Authors: L. Aluigi, F. Alimenti, L. Roselli, T.T. Thai, M.M. Tentzeris

ABSTRACT:
A new contactless assembly method for SoC wireless transceivers and antennas on flexible and paper substrates is presented. An Archimedean spiral antenna, matched to an heterogeneous transformer which couples the received power to the chip has been simulated at 1.5 GHz. Finally, as a proof-of-concept a prototype is fabricated and experimented. The measurement of the whole structure (antenna and transformer) shows a |S11| of about -12 dB at 1.5 GHz, in a fair good agreement with simulations.
