What Is a Horn Antenna?
A horn antenna is an antenna used for receiving or transmitting electromagnetic waves such as radio waves or microwaves.
Named for its shape, which typically resembles a horn or cone with flared sides or a widened tip, it is known as a horn antenna. Its horn-shaped structure allows it to efficiently receive or transmit electromagnetic waves and focus them in a specific direction. Key features include the ability to process signals over a wide bandwidth and high directivity, meaning it can strongly concentrate the reception or transmission of electromagnetic waves in a specific direction.
Horn antennas are primarily used in the microwave region and find applications in fields such as communication, radar, satellite communication, and wireless communication.
