Design of waveguide-fed profiled smooth conical horn associated with dielectric lens antenna for sub-THz application

Abstract

This thesis investigates the design of a profiled smooth conical horn antenna integrated with a dielectric lens for sub-THz applications. The aims to address challenges in high-frequency antenna design, such as propagation losses, and diffraction. A smooth conical horn geometry is developed to enhance radiation efficiency and minimize diffraction. The dielectric lens is incorporated to focus waves, improving gain and directivity. Simulations using CST Studio Suite are employed to model and the antenna, evaluating key performance metrics such as gain, radiation patterns, and efficiency. The system demonstrates broadband compatibility and efficient energy , making it suitable for sub-THz and radar systems. This work offers a scalable solution for next-generation antenna technologies, providing a foundation for further exploration in advanced high-frequency systems.
