Yagi

Yagi is a type of directional antenna commonly used in space and astronautical engineering for communication purposes. It consists of a driven element, a reflector, and one or more directors. The driven element is connected to the transmitter or receiver and generates the radio waves. The reflector is placed behind the driven element and reflects the radio waves forward, while the directors are placed in front of the driven element and focus the radio waves in a specific direction. Yagi antennas are used in various space applications, such as satellite communication, deep space communication, and radio astronomy.
