For taking antenna far field pattern, what must be the distance r , between transmitting and receiving antennas
Answers
The FRIIS Transmission Formula:
The FRIIS Transmission Formula is usually used to measure distance between transmitor and receiver antenna in the field of telecommunication engineering.
According to FRIIS Transmission equation,
Pr = ( Pt.Gt.Gr.λ²) / (4π.R)²
Where, Pr = Power at the receiving antenna
Pt = Output power of transmitting antenna
Gt = Gain of transmitting antenna
Gr = Gain or receiving antenna
λ = Wavelength ( λ = 1/f)
R = Distance between transmitting and receiving antenna
*So, we can see, deriving R from the FRIIS transmission formula we can measure the distance between transmitting and receiving antenna.
