Yagi Uda Antennas

The Yagi antenna, also known as the Yagi-Uda antenna, is a directional antenna developed by Shintaro Uda and later popularized by Professor Yagi. This antenna type is widely known for its unique design consisting of a single driven element, typically a dipole or folded dipole, and additional parasitic elements which include a reflector and one or more directors. These elements are rods connected to the antenna in a linear array.

The driven element is the active part of the Yagi antenna and is where the transmission line connects. It radiates signals and receives signals. In contrast, the parasitic elements, the reflector, and director(s) are not directly connected to the transmission line but play a crucial role in the antenna's performance. The reflector element is usually placed behind the driven element and is slightly longer. Its primary purpose is to reflect radio waves to enhance the antenna's power in a specific direction. On the other hand, director elements, which are usually shorter and placed in front of the driven element, help focus the radio waves in a particular direction, increasing the antenna's gain and directionality.
