Q. Which of the following statement about antenna array is false?

(A) field pattern is the product of individual elements in array
(B) field pattern is the sum of individual elements in array
(C) resultant field is the vector superposition of the fields from individual elements in array
(D) high directivity can be achieved for long distance communications

💬 Discuss

✅ Correct Answer: (B) field pattern is the sum of individual elements in array

Explanation: the total resultant field is obtained by adding all the fields obtained by the individual sources in the array. radiation pattern is obtained by multiplying the individual pattern of the element. field pattern is the product of individual elements in array. antenna arrays are used to get high directivity with less side lobes.
