29. Amongst which of the following shows the relation between half power beam width and the directivity of an antenna?
- A larger HPBW equates to more directivity
- A smaller HPBW equates to more directivity
- A smaller HPBW equates to less directivity
- None of the above
Answer: B) A smaller HPBW equates to more directivity.
Explanation:
The antenna's directivity and HPBW are inversely related; narrower HPBW equates to higher directivity, indicating that the antenna is more focused in a certain direction.
