To design and develop an indigenous, compact, and high-performance multi-functional antenna system capable of supporting communication, navigation, surveillance, and electronic warfare across multiple frequency bands for naval platforms including ships, submarines, and UAVs. Naval platforms require multiple antennas for various tasks like SATCOM, GPS, UHF/VHF communication, radar, and EW. However, separate antennas for each function result in space constraints, mutual interference, increased maintenance, and high radar cross-section. A unified multi-functional antenna can resolve these challenges by integrating multiple capabilities into a single low-profile system.
