What is meant by antenna bandwidth?
- AAntenna length divided by the number of elements
- BThe angle between the half-power radiation points
- CThe angle formed between two imaginary lines drawn through the ends of the elements
- DThe frequency range over which the antenna may be expected to perform well
Correct answer: D — The frequency range over which the antenna may be expected to perform well. From the official ISED question bank, verified word for word.
Why
Antenna bandwidth describes the span of frequencies where your antenna works efficiently, meaning it can transmit and receive signals without needing constant adjustment as you tune across the band. The full explanation — and one for every question — is in Pro.
