The formula to calculate the Helical Antenna Length (L) is:
\[ \text{L} = \frac{\text{C} \cdot \lambda}{4 \cdot \pi} \]
Where:
Let's say the circumference of the helix (C) is 1 meter and the wavelength of the signal (λ) is 0.5 meters. Using the formula:
\[ \text{L} = \frac{1 \cdot 0.5}{4 \cdot 3.14159} \approx 0.04 \, \text{meters} \]
So, the length of the helical antenna is approximately 0.04 meters.
