What is the radiation pattern of a dipole antenna in free space in a plane containing the conductor?
It is a figure-eight at right angles to the antenna✓Правильный ответ
It is a figure-eight off both ends of the antenna
It is a circle (equal radiation in all directions)
It has a pair of lobes on one side of the antenna and a single lobe on the other side
Объяснение
A dipole radiates most strongly broadside to the wire and has nulls off its ends, so the pattern in the plane containing the conductor is a figure eight whose lobes point at right angles to the antenna.
