A vertical whip antenna has a radiation pattern best described by?

• A. A Direct Beam
• B. A Square Pattern
• C. A Circle
• D. An Omnidirectional Pattern

Answer: (C)

A vertical whip radiates energy in a symmetric way around its axis, so in the horizontal plane the pattern is the same in all directions. That means the radiation pattern around the compass is uniform, which in 3D appears as a donut shape with stronger energy to the sides and less directly above or below. In practical terms, this is described as an omnidirectional pattern: it radiates equally in all directions around the antenna. The idea isn’t a single directed beam or a square shape; the plan view may look circular, but the formal description is omnidirectional.
