Feb 26, 2024 · The Yagi-Uda antenna, also known as Yagi antenna, catches TV and radio signals. Invented by Japanese scientists Hidetsugu Yagi and Shintaro Uda in the 1920s, it’s great at sending signals in one direction. Useful for improving TV signals, ham radios, radar, and satellite communication.
A Yagi–Uda antenna, or simply Yagi antenna, is a directional antenna consisting of two or more parallel resonant antenna elements in an end-fire array; these elements are most often metal rods (or discs) acting as half-wave dipoles.
Yagi-Uda antenna is the most commonly used type of antenna for TV reception over the last few decades. It is the most popular and easy-to-use type of antenna with better performance, which is famous for its high gain and directivity
May 11, 2022 · Yagi Uda antenna is also termed as Yagi antenna which is a directional antenna that has either two or more parallel resonant antenna components acting as half-wave dipoles.
A Yagi-Uda antenna is formed by a combination of 3 major elements i.e., driven element, reflector and directors. These are basically designed to operate in very high and ultra-high frequency bands and offers the operating frequency ranging between 30 MHz to 3 GHz.
The Yagi-Uda antenna or Yagi Antenna is one of the most brilliant antenna designs. It is simple to construct and has a high gain, typically greater than 10 dB. The Yagi-Uda antennas typically operate in the HF to UHF bands (about 3 MHz to 3 GHz), although their bandwidth is typically small, on the order of a few percent of the center frequency.
The design of a Yagi-Uda antenna is actually quite simple. Because Yagi antennas have been extensively analyzed and experimentally tested, the process basically follows this outline: Look up a table of design parameters for Yagi-Uda antennas. Build the Yagi (or model it numerically), and tweak it till the performance is acceptable
