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

Electrical size of antenna is increased by which of the following? Correct Answer Antenna Array

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.
