Yagi Antenna Design
To design a Yagi-Uda antenna effectively, specific design specifications should be adhered to:
Component |
Length range |
---|---|
Driven Element |
0.458λ to 0.5λ |
Reflector |
0.55λ to 0.58λ |
Directors |
|
Spacing between Directors |
0.2λ |
Reflector to Dipole Spacing |
0.35λ |
Dipole to Director Spacing |
0.125λ |
By following these specified dimensions, one can successfully design a Yagi-Uda antenna.
Yagi-Uda Antenna
The Yagi-Uda antenna, also known as Yagi antenna, catches TV and radio signals. Invented by Japanese scientists Hidetsugu Yagi and Shintaro Uda in the 1920s, it’s great at sending signals in one direction. Useful for improving TV signals, ham radios, radar, and satellite communication. Works best in specific places needing strong and focused signal coverage. This article covers its parts, qualities, design, and modern uses in communication and technology.
