23 kwi 2024 · The Yagi antenna works on the principle of wave amplification, in which the dipole absorbs and radiates the signal. The directors help amplify the radiation of the signal in a particular direction while the reflector reflects the signal in the opposite direction, thus increasing the forward gain.
26 lut 2024 · The Yagi antenna, also known as a Yagi-Uda antenna, is a directional antenna system primarily used for communications and broadcasting. It was invented in the 1920s by Japanese engineers Shintaro Uda and Hidetsugu Yagi.
The word "Yagi" is used to describe a type of antenna and is credited to very famous Japanese antenna experts by the names of Yagi and Uda! Most hams refer to this type of antenna as the "Yagi" rather than use both men's names.
In the next section, we'll explain the principles of the Yagi-Uda antenna. The basic geometry of a Yagi-Uda antenna is shown below in Figure 1. Figure 1. Geometry of Yagi-Uda antenna. The Yagi antenna consists of a single 'feed' or 'driven' element, typically a dipole or a folded dipole antenna.
2 paź 2024 · In the realm of Yagi antennas, the LFA Yagi is a cutting-edge product carefully crafted to redefine the possibilities of Yagi designs. Its transformative features, which include a unique closed dipole loop fed element, three-dimensional optimisation, direct 50 Ω feed and an innovative DC to earth connection, have catapulted the LFA Yagi to the ...
