Q. Electrical size of antenna is increased by which of the following?

  • (A) antenna array
  • (B) decreasing the coverage area
  • (C) increasing the coverage area
  • (D) using a single antenna

✅ Correct Answer: (A) antenna array
Explanation: to increase the directivity antenna arrays are used. with the antenna arrays, directivity and gain increases and beam width decreases. the electrical size of the antenna is increased by placing an array antenna together to achieve high directivity.
