Antenna Gain Solution

STEP 0: Pre-Calculation Summary

Formula Used

Antenna Gain = Radiation Intensity/Isotropic Radiation Intensity
G = U/U_o
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/U_o --> 27/0.09

Evaluating ... ...

G = 300

STEP 3: Convert Result to Output's Unit

300 --> No Conversion Required

FINAL ANSWER

300 <-- Antenna Gain
