Some advantages of the Yagi- Uda Antenna include that this is a widely used design and low cost. The construction also is simple. Some disadvantages are that the receiver of the Yagi-Uda Antenna may have problem receiving signal.

Who discovered the antenna?
yagi uda
Is parasitic elements are used in yagi-uda antenna?
Yes - reflector element and directional elements.
How many directors and reflectors in Yagi Uda antenna?
yagi udda antenna has only one reflector...but it has many directors...depending upon gain and efficiency...the length of reflector is normally...more than one-half of wavelength... and directors have a length less than one-half of wavelength...
What is the difference between yagi antenna and dipole antenna?
I don't think it has. Bandwidth depends on the diameter to length ratio of the antenna. The greater the diameter of the elements the wider the bandwidth. The inductance goes down and the capacitance goes up, giving the antenna a lower Q. the folded dipole has a greater effective diameter (at least double for the same materials). You can increase a normal dipole's bandwidth by increasing the diameter, hence the old time birdcage aerials.
Why dipole antenna not used for high frequency?
Depends on what you mean by high frequency. The rabbit ears antenna used in broadcast TV is a dipole and is used for VHF.
Who discovered the antenna?
yagi uda
What is a Yagi-Uda antenna?
how to measure the length of elements and spacing of elements
What are the disadvantage of yagi-uda antenna?
bandwidth is less..
Is parasitic elements are used in yagi-uda antenna?
Yes - reflector element and directional elements.
Is yagi uda antenna have parasitic elements?
Yes, the Yagi-Uda antenna has several parasitic elements, in the form of a reflector ("behind" the driven element) and the directional elements ("in front" of the driven element).
Element of Yagi-Uda antenna?
A Yagi-Uda directional antenna consists of a driven element (a dipole), and one or more parasitic elements -- a reflector (5% larger than the driven element) and directional elements (5% shorter than the driven element). This difference helps increases the gain and directionality of the antenna in the desired direction.
What are the advantage of Yagi-uda array?
The Yagi array allows a significant increase in antenna gain (expressed in dBi or Db over isotropic) by the simple addition of parasitic elements to a dipole or folded dipole.
Is that yagi uda has high bandwith?
no..it has less bandwidth
How many directors and reflectors in Yagi Uda antenna?
yagi udda antenna has only one reflector...but it has many directors...depending upon gain and efficiency...the length of reflector is normally...more than one-half of wavelength... and directors have a length less than one-half of wavelength...
What is a Yagi antenna?
A yagi is a directional antenna consisting of two or more dipoles.
Is a Yagi antenna a directional antenna?
Yes.
Where is the yagi antenna used?
mainly it is used in transmission and reception of TV signals
