What are the applications of Yagi Uda antenna?
It is a highly directional antenna and widely used in to receive TV signals. Now a day’s Yagi -Uda antennas are also used in the fields of RADARs, satellites and RFID applications [2]. It consists of a dipole, reflector and directors.
Who invented Yagi-Uda?
Hidetsugu Yagi
Shintaro Uda
Yagi–Uda antenna/Inventors
The solution came in 1926 from two professors at Tohoku Imperial University in Japan — Hidetsugu Yagi (Fig. 1) and Shintaro Uda — who devised the famous Yagi–Uda antenna1,2,3.
Which antenna is used in Yagi-Uda?
Explanation: Folded dipole produces flatter impedance v/s frequency compared to single dipole. So, folded dipole is used in Yagi-Uda to obtain wider frequency range. 7.
What is Yagi-Uda antenna explain its constructional details and working in detail?
A Yagi-Uda antenna has 3 main elements that combinedly form its structure. These 3 major elements are driven element which is generally a half-wave folded dipole, a reflector and directors. The structure contains one driven element and a reflector while directors can be more than one.
What is antenna Yagi-Uda antenna in detail?
Yagi–Uda antennas consist of a single driven element connected to a radio transmitter and/or receiver through a transmission line, and additional “parasitic elements” with no electrical connection, usually including one so-called reflector and any number of directors.
What are the advantages of Yagi-Uda antenna?
Advantages of yagi UDA antenna: It is a compact size and also it is must in lightweight. It offers wide bandwidth due to the use of folded dipole. It is lower cost because easy of handling and maintenance. It offers a unidirectional radiation pattern which is reasonably good.
When was Yagi Uda created?
1926
Yagi’s invention was ahead of its time (patented in 1926) and therefore not understood in Japan. Its value was, however, accepted in Europe and North America, where it entered commercial production.
When was the Yagi antenna invented?
The Yagi antenna was invented in Japan, with results first published in 1926. The work was originally done by Shintaro Uda, but published in Japanese.
