Beam Width between First Null (BWFN) Endside Array Solution

STEP 0: Pre-Calculation Summary

Formula Used

Beam Width between First Null Endside Array = 2*sqrt((2*Broad Side Array Wavelength)/(Number of Turns of Array Antenna*Distance))
BW_end = 2*sqrt((2*λ_b)/(N*d))
This formula uses 1 Functions, 4 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Beam Width between First Null Endside Array - (Measured in Radian) - Beam Width between First Null Endside Array refers to the angular span between the first pattern nulls adjacent to the main lobe.
Broad Side Array Wavelength - (Measured in Meter) - Broad Side Array wavelength is the distance between adjacent crests in the adjacent cycles of a waveform signal propagated along a wire.
Number of Turns of Array Antenna - Number Of Turns Of Array Antenna is the number of identical parallel antennas are arranged along a line.
Distance - (Measured in Meter) - Distance at the which the identical parallel antennas are arranged along a line at equal distances.

STEP 1: Convert Input(s) to Base Unit

Broad Side Array Wavelength: 90.01 Meter --> 90.01 Meter No Conversion Required
Number of Turns of Array Antenna: 6 --> No Conversion Required
Distance: 10 Meter --> 10 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

BW_end = 2*sqrt((2*λ_b)/(N*d)) --> 2*sqrt((2*90.01)/(6*10))

Evaluating ... ...

BW_end = 3.46429405988195

STEP 3: Convert Result to Output's Unit

3.46429405988195 Radian -->198.489428623514 Degree (Check conversion here)
