Dielectric Rod Waveguide-based Radio-Frequency interconnect operating from 55 GHz to 340 GHz

We present a novel concept for high-frequency interconnects based on dielectric rod waveguide structures, which show a broadband operating frequency range. The low cut-off frequency is set at 50 GHz by design, while the upper limit extends beyond 340 GHz. An experimental demonstration is presented to validate the concept. The presented RF interconnect approach covers several rectangular waveguide bands with potential to be extended to terahertz range.
