An antenna is a device used to receive or transmit radio, television, or other signals. It works by capturing electromagnetic waves, such as those sent by TV stations, radio stations, or cell towers, and converting them into electrical signals that can be processed by a television, radio, or other equipment. Antennas can be external, like a rooftop antenna for television, or built into devices, such as a smartphone. They are essential for receiving over-the-air broadcasts, wireless communications, and other forms of signal transmission.
