Antenna Gain Solution

STEP 0: Pre-Calculation Summary
Formula Used
Antenna Gain = Radiation Intensity/Isotropic Radiation Intensity
G = U/Uo
This formula uses 3 Variables
Variables Used
Antenna Gain - Antenna Gain is the maximum power gained by antenna.
Radiation Intensity - (Measured in Watt per Steradian) - Radiation Intensity refers to the power radiated per unit solid angle by an antenna in a specific direction.
Isotropic Radiation Intensity - (Measured in Watt per Steradian) - Isotropic Radiation Intensity refers to the radiation intensity of an idealized isotropic radiator.
STEP 1: Convert Input(s) to Base Unit
Radiation Intensity: 27 Watt per Steradian --> 27 Watt per Steradian No Conversion Required
Isotropic Radiation Intensity: 0.09 Watt per Steradian --> 0.09 Watt per Steradian No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
G = U/Uo --> 27/0.09
Evaluating ... ...
G = 300
STEP 3: Convert Result to Output's Unit
300 --> No Conversion Required
FINAL ANSWER
300 <-- Antenna Gain
