Exercice Corrige Faisceaux Hertziens: Pdf

θ = 1 0 ∘ = 0.1745 rad

Faisceaux Hertziens, also known as Hertzian beams or radio beams, are a crucial concept in the field of telecommunications and electromagnetic theory. In this article, we will provide a detailed explanation of Faisceaux Hertziens, along with a solved exercise in PDF format.

A Faisceau Hertzien is operating at a frequency of 10 GHz, with a wavelength of 3 cm. If the beamwidth of the Faisceau Hertzien is 10°, what is the distance between the transmitter and receiver if the signal strength decreases by 20 dB over a distance of 10 km? exercice corrige faisceaux hertziens pdf

D = 0.1745 2.44 × 0.03 ​ = 4.2 km

Substituting the values:

d = 10 km × 10 20 ​ ​ = 14.14 km

Rearranging the formula to solve for \(d\) : θ = 1 0 ∘ = 0

So
