Directivity Of Antenna Solution

STEP 0: Pre-Calculation Summary
Formula Used
directivity_antenna = Max Radiation Intensity/Avg Radiation Intensity
D = Rmax/Ravg
This formula uses 2 Variables
Variables Used
Max Radiation Intensity - Max Radiation Intensity of an antenna is specified for a given polarization of the field. (Measured in Rad per Second)
Avg Radiation Intensity - Avg Radiation Intensity is the average intensity of radiation (Measured in Rad per Second)
STEP 1: Convert Input(s) to Base Unit
Max Radiation Intensity: 10 Rad per Second --> 0.1 Gray per Second (Check conversion here)
Avg Radiation Intensity: 4 Rad per Second --> 0.04 Gray per Second (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
D = Rmax/Ravg --> 0.1/0.04
Evaluating ... ...
D = 2.5
STEP 3: Convert Result to Output's Unit
2.5 Decibel --> No Conversion Required
FINAL ANSWER
2.5 Decibel <-- directivity of antenna
(Calculation completed in 00.015 seconds)
