Q. If the beam width of an antenna in two orthogonal planes are 300 and 600. Then the directivity of the antenna is:

  • (A) 24
  • (B) 18
  • (C) 36
  • (D) 12

Explanation by: Admin

given the beam width of the antenna in 2 planes, the directivity is given by 32400/θ*∅, where θ,∅ are the beam widths in the two orthogonal planes. substituting in the equation, directivity of the antenna is 18.
