Consider a loss less antenna with a directive gain of + 6 dB. If 1 mW of power is fed to it the total power radiated by the antenna will be

[A].	4 mW
[B].	1 mW
[C].	7 mW
[D].	1/4 mW

Answer: Option A

Explanation:

6 dB = 10 log₁₀ 217-415-1

1-sym-imp 217-415-1

10^0.6 1-sym-imp 3.98

P_r = 3.98 mW.
