A Slotted Elliptical Patch Antenna for Six Generation Communication System in Terahertz Band

The advancement of wireless communication toward 6G networks necessitates the development of antennas that can function at terahertz (THz) frequencies (0.1-10 THz). This is essential to satisfy the growing need for rapid data transmission and minimal latency connectivity. However, conventional antenna designs often fail to deliver the required bandwidth, gain, and efficiency at these elevated frequencies, which constrains their applicability for 6G technologies. This research introduces the design and development of a multi-slotted elliptical patch antenna specifically optimized for 6G systems operating in the THz band. The primary objective is to enhance the antenna’s performance, making it well-suited for high-frequency applications. The antenna is constructed on a Roger 5880 substrate with a dielectric constant of 2.2, a tangent loss of 0.0009, and a thickness of 6 µm. It measures precisely 140 × 100 µm². A 50-ohm microstrip feedline excites the antenna, ensuring optimal power transfer. Simulations conducted with Computer Simulation Technology software yield promising outcomes, showcasing a return loss (\(S₁₁\)) of −27.08 dB, a broad operational bandwidth of 1.25 THz (2.12-3.37 THz), a gain of 7.769 dB, directivity of 8.613 dB, and an efficiency of 89%. This multi-slotted elliptical patch antenna exhibits remarkable potential for 6G applications, offering a robust solution to meet the demands of forthcoming THz communication systems. Its superior performance positions it as an ideal candidate for high-speed communication networks, propelling the advancement of the next generation of wireless technology.
