2.2. The Fresnel Zone

For a link to be considered "Line of Sight," it is not sufficient for the antennas to barely see each other. The majority of the radio energy travels not in a straight line, but within an ellipsoid volume surrounding the direct path, known as the First Fresnel Zone.

Exercise 1: Fresnel Zone Clearance

Q: A 10 km link at 7.5 GHz has an obstacle 4 km from the transmitter. Calculate the 1st Fresnel zone radius at that point and determine if 60% clearance is achieved if the obstacle is 20 m below the line of sight. The study of Transmission par Faisceaux Hertziens (Microwave
