| 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 |
| Answer» B. 18 | |
| Explanation: 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. | |
