Question
Radiation resistance of an antenna is 54 ? and loss resistance is 6 ?. If antenna has power gain of 10, then directivity is:
Options
A. 9
B. 11.11
C. data not sufficient
D. 10

Correct Answer

11.11

Explanation

Efficiency of antenna

Radiation resistance of an antenna is 54 ? and loss resistance is 6 ?. If antenna has power gain of

Power gain = 10

Thus directivity Radiation resistance of an antenna is 54 ? and loss resistance is 6 ?. If antenna has power gain of .
