What is Yagi-Uda Antenna?

The Yagi antenna is also called the Yagi-Uda antenna. It is a type of antenna which is used to catch TV signals and radio waves. It was made by Japanese scientists Hidetsugu Yagi and Shintaro Uda in the 1920s....

Components of Yagi-Uda Antenna

Driven Element: In the Yagi-Uda antenna, the driven element is vital for signal transmission and reception. It interacts with electromagnetic waves, facilitating effective communication. Reflector: Strategically placed behind the driven element, the reflector significantly enhances the antenna’s performance. It acts passively, redirecting and focusing incoming signals toward the driven element to improve reception. Directors: Positioned in front of the driven element, directors are additional elements that collaborate to enhance the antenna’s directional capabilities. By carefully adjusting the number and spacing of directors, the antenna efficiently amplifies signals in the desired direction, resulting in improved reception quality....

Yagi Uda Antenna Working & Construction

To construct a Yagi-Uda antenna, se­veral components come toge­ther to create an e­fficient and directional antenna for transmitting or re­ceiving electromagne­tic signals. The central ele­ment is called the “boom,” which se­rves as the framework for mounting all othe­r parts. Connected to the transmission line­ is the primary eleme­nt, known as the “driven ele­ment,” responsible for signal transmission or re­ception. At the far end of the antenna is the “reflector,” a longer element that reflects energy towards the antenna’s radiation pattern. In front of the driven element, there are multiple strategically placed “directors” with specific lengths and spacings. These directors assist in directing the antenna’s radiation pattern for optimal performance....
