An antenna changes electrical signals into radio waves.This section explains how antennas move energy into space. : The shape of the radio wave. Antenna Gain : How well the antenna directs power. Beam Width : The angle of the main radio beam. 2. Types of Antennas Different tasks need different shapes of antennas. Wire Antennas : Simple wires used for radio. Aperture Antennas : Horn shapes used for microwaves. Array Antennas : Groups of antennas working together. 3. Wave Propagation Waves travel through the air in different ways. Ground Waves : Waves that follow the curve of the Earth. Space Waves : Line-of-sight waves like satellite TV signals. Sky Waves : Waves that bounce off the upper atmosphere. Who Should Read It?
