Nozzle location (continued)
Beam angle
• Beam angle is the width of the cone
• The peak energy density is directly in front
• There is a signal transmitted outside the
Emission Cone
• Keep emission cone free of interference
• Locate the antenna away from the side
• Make allowance for the emission cone spreading: beam angle depends on horn size.
