The horn antenna is also among the most reliable forms of antennas in microwave and radio frequency applications. It is designed to steer radio waves while maintaining a high signal strength. The flared shape of the horn helps concentrate energy in a specific direction, making it essential for performance in testing, communication, and measurement applications. Its simplicity, reliability, and the fact that it can operate over a broad frequency range make its use preferable in industries that require stable and precise results.
