Helix Circumference of Helical Antenna Solution

STEP 0: Pre-Calculation Summary

Formula Used

Helix Circumference = Input Impedance/140
C_λ = Z_h/140
This formula uses 2 Variables

Variables Used

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.
Input Impedance - (Measured in Ohm) - The Input Impedance can be calculated as the current travels along the antenna and the phase varies continuously.

STEP 1: Convert Input(s) to Base Unit

Input Impedance: 112 Ohm --> 112 Ohm No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

C_λ = Z_h/140 --> 112/140

Evaluating ... ...

C_λ = 0.8

STEP 3: Convert Result to Output's Unit

0.8 Meter --> No Conversion Required

FINAL ANSWER

0.8 Meter <-- Helix Circumference
