Helical Antenna Length Calculator

Formula

The formula to calculate the Helical Antenna Length (L) is:

\[ \text{L} = \frac{\text{C} \cdot \lambda}{4 \cdot \pi} \]

Where:

Helical Antenna: A specialized type of antenna designed to radiate and receive electromagnetic waves in circular or elliptical polarization.
Circumference of the Helix (C): The distance around the helix.
Wavelength of the Signal (λ): The distance over which the wave's shape repeats.
π: A mathematical constant (approximately 3.14159).

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.
