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 research 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 electromagnetic waves, improving gain and directivity. Simulations using CST Studio Suite are employed to model and optimize the antenna, evaluating key performance metrics such as gain, radiation patterns, and efficiency. The combined system demonstrates broadband compatibility and efficient energy concentration, making it suitable for sub-THz communication 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.
