Abstract: This study provides a comparative analysis of four types of antennas—parabolic reflector, phased array with mechanical and electronic scan types, and Cassegrain antennas—focusing on critical performance metrics such as side lobe levels, gain, and efficiency. The research highlights the differences in side lobe suppression, gain, and overall efficiency across these antenna types. Parabolic reflector antennas are known for their high gain but tend to have moderate side lobe levels. Phased array antennas, which can be equipped with either mechanical or electronic scanning, offer improved side lobe suppression and higher efficiency, making them highly adaptable for various applications. Cassegrain antennas, which utilize a combination of a parabolic primary reflector and a secondary reflector, are particularly effective in minimizing side lobe levels while maintaining good gain and efficiency. These results were achieved with the help of the PREP software, a powerful simulation tool for radar system performance analysis. This analysis emphasizes the trade-offs between side lobe suppression, gain, and efficiency when selecting the most suitable antenna for different communication and radar systems, particularly for high-frequency applications. The findings suggest that antenna selection should be tailored to specific application requirements, with a focus on achieving optimal performance in terms of directivity, interference reduction, and energy efficiency.
