Feed antennas are specialized devices used to direct radio waves toward a larger antenna, often referred to as a reflector. They play a crucial role in enhancing signal strength and quality in various communication systems, including satellite and radar applications. By focusing the radio waves, feed antennas help improve the overall efficiency of the system. These antennas come in various designs, such as horn antennas and parabolic feed antennas, each suited for specific applications. Their primary function is to ensure that the transmitted or received signals are concentrated in a particular direction, minimizing interference and maximizing performance.
