If an antenna has a directivity of 16 and radiation efficiency of 0.9, then the gain of the antenna is:

If an antenna has a directivity of 16 and radiation efficiency of 0.9, then the gain of the antenna is: Correct Answer 16.2

Gain of an antenna is given by the product of radiation efficiency of the antenna and the directivity of the antenna. Product of directivity and efficiency thus gives the gain of the antenna to be 16.2.
