10-Gbit/s Data Transmission over Dielectric Sheet for 120-GHz-band Sheet LAN

We investigated 120-GHz-band sheet LAN that enables the connection to LAN simply by placing portable devices on the sheet and can achieve 10-Gbit/s data transmission. We designed dielectric sheets and waveguide-to-dielectric sheet transition, and evaluated their transmission losses. The transmission loss over 100-mm-long dielectric sheet was about -6 dB at the 120 GHz band. We have succeeded in 10-Gbit/s data transmission over the dielectric sheet using 120-GHz wireless signal.
