Design and Investigation of Terahertz Antennas for 5G and beyond 5G

Abstract

The Terahertz (THz) band of frequencies (0.1-10 THz) help to overcome the spectrum newlinescarcity limitation of the current wireless network, by providing large bandwidth and data newlinerate and fills the gap between electronics and photonics. Terahertz communication is a newlinepromising technology that could potentially revolutionize wireless communications. newlineVarious antenna designs with characteristics that are suitable for short range THz newlinecommunication, including 5G and beyond are presented in this research work. The study newlineaims numerous design techniques that are used to create high performance THz antennas. newlineIt also aims to look at cutting-edge techniques for designing terahertz antennas exhibiting newlineboth linear and circular polarization. Different kinds of compact planar antennas newlineexhibiting wide bandwidth with circular polarization are presented. The diverse antenna newlineconfigurations in this range of frequencies viz microstrip, slotted waveguide, substrate newlineintegrated waveguide, Yagi Uda, and Luneburg lens integrated with substrate lens newlineantennas are thoroughly investigated. THz antennas have several uses besides data newlinetransmission, including sensing, astronomy, imaging, detection, and spectroscopy. THz newlineantenna with wide axial ratio bandwidth with beam steering ability is another research newlineconcern. Investigation on antenna gain improvement in order to overcome the newlinepropagation loss has been carried out by embedding various techniques like slotted array newlineand patch array in the antenna design. Another area of focus in this research is the design newlineof THz antennas with beam steering capability which mitigates the multipath fading newlineissues and helps to precisely direct the beam to their intended destination. Innovative newlinetechniques of beam scanning with modified slotted array as well as with integration of newlineLuneburg lens and substrate lens are also illustrated. In all the research findings, critical newlineantenna parameters are simulated, verified and analyzed for optimum performance. newline
