There has been an increasing interest in the application of terahertz (THz) waves to broadband wireless communications. In particular, use of frequencies above 275 GHz is one of the strong concerns among radio scientists and engineers, because these frequency bands have not yet been allocated at specific active services, and there is a possibility to employ(More)
We report on the first error-free terahertz (THz) wireless communication at 0.310 THz for data rates up to 8.2 Gbps using a 18-GHz-bandwidth GaAs/AlGaAs field-effect transistor as a detector. This result demonstrates that low-cost commercially-available plasma-wave transistors whose cut-off frequency is far below THz frequencies can be employed in THz(More)
We have developed ultra-broad band THz receivers using polymeric substrate for multiband THz wireless communications. We demonstrate 1.5 Gbit/s error-free transmission for both 120 GHz and 300 GHz ranges. This is due to broad-band characteristics of a planar tapered slot antenna on low dielectric constant of the polymeric substrate.
