What are the advantages disadvantages and applications of Yagi Uda antenna?
Benefits or advantages of YAGI Antenna | YAGI UDA Antenna ➨It offers wide bandwidth due to use of folded dipole. ➨It offers unidirectional radiation pattern which is reasonably good. ➨It offers substantial increase in directivity and gain compare to simple dipole antenna. ➨It is lower in cost and simple to build.
How does a Yagi aerial work?
Yagi antennas use mutual coupling between standing-wave current elements to produce a traveling-wave unidirectional pattern. It consists of an array of a dipole and additional closely coupled parasitic elements. The elements in the Yagi antenna are usually welded to a conducting rod or tube at their centers.
Why is Yagi-Uda antenna used?
The Yagi antenna or aerial sometimes called the Yagi-Uda antenna is widely used where gain and directivity are required from an RF antenna design. The Yagi antenna or Yagi-Uda antenna or aerial is a particularly popular form of antenna where directivity and gain are required.
What are the disadvantages of Yagi-Uda antenna?
Disadvantages of yagi UDA antenna:
- It is sensitive to frequency.
- It does not offer very high gain limited around 20 dB.
- The design is obstructive in nature.
- Bandwidth is reduced if a number of director element is used in the array.
- Need a large number of elements to be used.
- It is prone to noise.
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.
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).
Do Yagi antennas need line of sight?
The Yagi antenna is a powerful form of directional antenna that may enhance cell phone and Wi-Fi reception. Because it relies on clear line-of-sight for optimum results, aiming a Yagi antenna requires precision to ensure it’s pointed directly at its desired signal source.
