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 directors in antenna?
Directors in an antenna are elements that enhance the antenna's directivity and gain. Typically used in Yagi-Uda antennas, directors are placed in front of the driven element and are usually shorter than it. They work by focusing the radiated energy in a specific direction, improving performance in that direction while reducing it in others. This results in a more efficient antenna for applications like communication and broadcasting.
Why does a yagi uda antenaa always have an odd number of elements?
A Yagi-Uda antenna typically has an odd number of elements to ensure proper impedance matching and to enhance its directional characteristics. The driven element, which is usually a dipole, is flanked by one or more parasitic elements—reflectors and directors—that work together to focus the antenna's radiation pattern. Having an odd number of elements allows for a balanced configuration, optimizing gain and minimizing side lobes while maintaining a stable feedpoint impedance. This design also helps in achieving better front-to-back ratios and overall efficiency.

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.
What are the parts of an yugi-uda antenna?
directors and receivers are the main part of a yagi uda anteena there can be many directors and receivers as more receivers will surely increase our gain but we use only one receiver because the gain will not increase much but the cost will surel increase
Is a Yagi antenna a directional antenna?
Yes.
