A Yagi-Uda antenna, commonly known as a Yagi antenna, is a directional antenna that consists of multiple parallel elements in a line. Typically, these elements include a single driven element connected to the transmission line, along with additional parasitic elements such as reflectors and directors. These antennas are widely used for their high gain and directivity, making them ideal for applications in radio and television broadcasting, and increasingly, in nanotechnology applications.
