In free space, what is the radiation pattern of a half-wave dipole?
- A Maximum radiation broadside from the antenna
- B Maximum radiation from the ends of the antenna
- C Omnidirectional radiation pattern
- D Hemispherical radiation pattern
Correct answer: A — Maximum radiation broadside from the antenna. From the official ISED question bank, verified word for word.
Why
A half-wave dipole radiates most strongly from its sides, perpendicular to the wire, which is called broadside. The full explanation — and one for every question — is in Pro.
