The present Master’s Thesis project in electronic engineering focuses on the in-depth analysis and precise design of High Frequency (HF) antenna, taking into consideration both ideal and challenging operational conditions. Building upon the CMV-605E antenna as a fundamental reference point, the endeavor entails the creation of a comprehensive Computer-Aided Design (CAD) model for the radiating structure, followed by a rigorous testing phase employing advanced electromagnetic simulation software. This research holds substantial significance within the military context and is carried out through a collaborative effort between the prestigious LINKS Foundation and Centro Polifunzionale di Sperimentazione (CEPOLISPE), an institute dedicated to research and experimentation within the Italian Army.
