Gain of Helical Antenna Solution

STEP 0: Pre-Calculation Summary

Formula Used

Helical Antenna Gain = 11.8+10*log10(Helix Circumference^2*Number of Turns of Helical Antenna*Turn Spacing)
G_a = 11.8+10*log10(C_λ^2*n*S)
This formula uses 1 Functions, 4 Variables

Functions Used

log10 - The common logarithm, also known as the base-10 logarithm or the decimal logarithm, is a mathematical function that is the inverse of the exponential function., log10(Number)

Variables Used

Helical Antenna Gain - (Measured in Decibel) - Helical Antenna Gain is the maximum power gained by antenna.
Helix Circumference - (Measured in Meter) - Helix circumference of an imaginary cylinder that the helix conductor is wound around expressed in wavelengths. The ideal value for a helical antenna is 1.0.
Number of Turns of Helical Antenna - Number Of Turns Of Helical Antenna is the number of identical parallel antennas are arranged along a line.
Turn Spacing - (Measured in Meter) - Turn Spacing in the antenna is the spacing between each turn of the antenna.

STEP 1: Convert Input(s) to Base Unit

Helix Circumference: 0.8 Meter --> 0.8 Meter No Conversion Required
Number of Turns of Helical Antenna: 6.01 --> No Conversion Required
Turn Spacing: 35.3 Meter --> 35.3 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

G_a = 11.8+10*log10(C_λ^2*n*S) --> 11.8+10*log10(0.8^2*6.01*35.3)

Evaluating ... ...

G_a = 33.1282915137445

STEP 3: Convert Result to Output's Unit

33.1282915137445 Decibel --> No Conversion Required

FINAL ANSWER

33.1282915137445 ≈ 33.12829 Decibel <-- Helical Antenna Gain
