Exercice Corrige Faisceaux - Hertziens Pdf

d = D × 1 0 20 L ​

D = 0.1745 2.44 × 0.03 ​ = 4.2 km

θ = 1 0 ∘ = 0.1745 rad

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?

d = 4.2 km × 1 0 20 20 ​ = 42 km

D = 20 K m ∗ 14 4.2 ​ = 6 K m
