YAGI AERIAL Meaning and
Definition
-
A Yagi aerial, also known as a Yagi-Uda antenna, is a type of directional antenna widely used in radio and television communications to capture and transmit electromagnetic waves. It is named after its inventors, Hidetsugu Yagi and Shintaro Uda.
The Yagi aerial consists of a generally straight conductor or dipole element, often referred to as the driven element, which is connected to the transmitter or receiver equipment. This driven element is surrounded by several other conductor elements, referred to as parasitic elements. These parasitic elements are typically shorter or longer than the driven element and are arranged in a specific pattern to achieve the desired directional characteristics of the antenna.
The Yagi aerial operates on the principle of wave interference and is designed to radiate or receive electromagnetic waves most effectively in a specific direction. It enhances the signal strength in its main lobe, which is the direction of maximum radiation, while reducing the reception or transmission in other directions, known as the side lobes. This directional focusing allows for better reception or transmission of signals from a specific source, improving the overall performance and range of communication.
Yagi aerials are commonly used in television reception, especially in areas with weak signal strength, as they can increase the incoming signal power. They are also utilized in amateur radio, Wi-Fi networks, and various other communication systems. The design and configuration of a Yagi aerial can vary depending on the desired frequency range, target source distance, and environmental factors, making it a versatile and widely adopted antenna for communication applications.

Etymology of YAGI AERIAL
The word "Yagi Aerial" is named after its inventor, Hidetsugu Yagi, a Japanese electrical engineer. In collaboration with his colleague Shintaro Uda, they developed a highly efficient directional antenna known as the Yagi-Uda antenna, or simply Yagi antenna. The antenna was first introduced in 1926, and its design has been widely used in the field of telecommunications and television broadcasting. Over time, the name "Yagi" became associated with this specific type of antenna. The term "aerial" is a British English term used to refer to an antenna that is used for receiving or transmitting radio signals. In American Engish, the term "antenna" is commonly used instead.
