Leaky-wave wires antenna for future D- band 6G communication systems

Future communication generation such as 6G and beyond will be utilizing the terahertz band, as this range promises potential benefits such as a high data rate. However, designing different electronic components for 6G is complicated and has low fabrication precision due to its small wavelength. Additionally, the cost is also very high as compared to 5G components. These antennas feature high data rates, small size, and high bandwidth and are a critical component for the communication system. Therefore, in this study, an antenna design is proposed for the future sub-THz communication system that operates at D- band which is proposed for the 6G communication system. The simulation analysis shows that the proposed antenna has a high gain of 9.9 dBi at 120 GHz operating frequency and good performance characteristics for the complete D-band. The design of the proposed antenna is simple, low-cost, and does not require any complex fabrication, and can be the potential leaky-wave antenna for future 6G if properly excite

Exploiting surface plasmon with dielectric coating in copper wires waveguide for the propagation of terahertz waves

Recently, metallic wires have gained popularity for utilization as waveguides in propagating sub-THz and THz waves through surface plasmonic polaritons (SPPs). Single and double metallic wire waveguides have demonstrated the ability to propagate these high frequencies with minimal loss and nearly zero dispersion. However, wires typically installed commercially are often coated with dielectric material. Therefore, this paper investigated the effects of using two and four metallic copper wires, both with and without dielectric coating. The impact of various gap distances on different propagation characteristics was also analyzed. Computer Simulation Technology (CST) Microwave Studio was employed in this study for electromagnetic simulations of both uncoated and coated configurations of two and four wires. The introduction of a dielectric coating led to an enhancement in reducing conductor losses and improving energy confinement, with the goal of enhancing the overall efficiency of waveguide signal propagation
