Yagi–Uda antenna
Hidetsugu Yagi/Inventions
The Yagi Antenna is a directional antenna invented by Dr. Hidetsugu Yagi of Tohoku Imperial University and his assistant, Dr. Shintaro Uta. This groundbreaking invention combined a simple structure with high performance.

Yagi–Uda antenna/Inventors
1920s: Yagi-Uda Antennas In 1926, Japanese inventor Shintaro Uda, with the help of his colleague, Hidetsugu Yagi, developed the Yagi-Uda antenna. Modern versions of this antenna are used on high frequency (HF), very high frequency (VHF), and ultra high frequency (UHF) bands due to its characteristically high gain.
Why is Yagi-Uda antenna used?
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. Directors provide directional capability to the antenna.
What type of antenna is the Yagi antenna?
directional antenna
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 acting as half-wave dipoles.
What does Yagi stand for?
: a highly directional and selective shortwave antenna consisting of a horizontal conductor of one or two dipoles connected with the receiver or transmitter and of a set of nearly equal insulated dipoles parallel to and on a level with the horizontal conductor.
Who invented first antenna?
The first antenna was devised by the German physicist Heinrich Hertz.
How far can a Yagi antenna reach?
How Far Can a Yagi Antenna Reach? A typical Yagi is effective up to 5 miles – but generally speaking will work best up to around 3. If you’re seeking to amplify cell signal, Yagi antennas come with either 50 or 75 ohm configurations, depending on the use case of your system (commercial or consumer usage).
What is inside Yagi antenna?
A Yagi antenna or a Yagi-Uda antenna, is a directional antenna that radiates signals in one main direction. It consists of a long transmission line with a single driven element consisting of two rods connected on either side of the transmission line. A typical Yagi antenna has one reflector and one or more directors.
Do Yagi antennas work?
The Yagi antenna is able to provide very useful levels of gain and front to back ratios. This causes the RF antenna to radiate more power in the opposite direction to this form of parasitic element. An element that does this is called a reflector. The element can be made inductive by tuning it below resonance.
Is Yagi a word?
Yes, yagi is in the scrabble dictionary.
Are antennas correct?
The plural noun form of “antenna” comes in two flavors: “antennas” and “antennae.” If you look up antenna in an English dictionary, you’ll see that the plural, antennas, is used to refer to electrical instruments, and antennae, to the protuberances found on the heads of insects.
What is the first antenna?
The first antennas were built in 1888 by German physicist Heinrich Hertz in his pioneering experiments to prove the existence of waves predicted by the electromagnetic theory of James Clerk Maxwell. Hertz placed dipole antennas at the focal point of parabolic reflectors for both transmitting and receiving.
