25. Which of the following formula is used to calculate the bandwidth of an antenna?

1. Bandwidth= Higher frequency* lower frequency
2. Bandwidth= Higher frequency+ lower frequency
3. Bandwidth= Higher frequency/ lower frequency
4. Bandwidth= Higher frequency- lower frequency

Answer: D) Bandwidth= Higher frequency- lower frequency

Explanation:

An antenna's bandwidth is the frequency range across which it can efficiently emit or receive electromagnetic waves. The formula to calculate the bandwidth of an antenna is: Bandwidth= Higher frequency* lower frequency.
