ICON3E- Investigating the Impact of Waveguide Curvature on the Characteristics of D-Band 6G Communication Systems

With an increase in users and devices, fast data rates are turning increasingly desirable in wired and wireless transmission. Moving towards higher frequency bands, especially in the multi-GHz region, is one potential solution to fulfil the user demands for a high data rate. Recently, it was demonstrated that using a waveguide technique and the higher order guide modes in the already established twisted pair cable, a data rate of terabits per second could be attained. The air-dielectric space inside the cable can be used to transmit the terahertz waves wirelessly. However, the idea is novel and there are quite challenges in the realization of this idea practically such as the bending effect and high attenuation due to the narrow gap. The copper wires and metallic foils inside the cable create an air space similar to the circular waveguide. Therefore, to investigate the feasibility of this cable for next-generation D band communication, a circular waveguide of similar dimensions is simulated, and the effect of bending on the propagation characteristics is studied. It is found that even a small bend in the waveguide structure has a significant effect on the performance of the waveguide. If this cable is properly excited, can be the revolutionary beginning of the high-speed internet and 6G.
