A new contactless assembly method for SoC wireless transceivers and antennas on flexible and paper substrates is presented. An Archimedean spiral antenna, matched to a heterogeneous transformer which couples the received power to the chip wirelessly has been simulated at 1.5 GHz. Finally, a proof-of-concept prototype was fabricated and experimented. The measurements of the complete structure including the antenna and the transformer show S 11 values of about -12 dB at 1.5 GHz.

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 a heterogeneous transformer which couples the received power to the chip wirelessly has been simulated at 1.5 GHz. Finally, a proof-of-concept prototype was fabricated and experimented. The measurements of the complete structure including the antenna and the transformer show S 11 values of about -12 dB at 1.5 GHz.File in questo prodotto:
