Yagi antenna, also known as Yagi-Uda antenna, is a type of directional antenna widely used in radio communication and television broadcasting. It was invented in 1926 by Japanese engineer Hidetsugu Yagi and his colleague Shintaro Uda. The Yagi antenna is characterized by its high gain, narrow beamwidth, and directional radiation pattern.
The Yagi antenna consists of a driven element, one or more parasitic elements, and a reflector element. The driven element is usually a dipole or a folded dipole, which is connected to the transmitter or receiver. The parasitic elements are passive elements that are not connected to the transmitter or receiver, but they interact with the electromagnetic field of the driven element and reflect or radiate energy. The reflector element is placed behind the driven element and helps to increase the directivity of the antenna.
The Yagi antenna is designed to operate at a specific frequency or a narrow band of frequencies. The length and spacing of the elements are critical to achieve the desired performance. The gain of the Yagi antenna is proportional to the number of parasitic elements and their spacing. The beamwidth of the Yagi antenna is inversely proportional to the number of parasitic elements and their spacing. The directional radiation pattern of the Yagi antenna is determined by the length and spacing of the elements and the presence of the reflector element.
