This converter estimates the key design parameters of a helical antenna based on the wavelength, number of turns (N), and spacing between turns (S). It provides details such as gain, diameter, beamwidth, and effective aperture, helping in efficient antenna design and optimization.
PINCH OFF VOLTAGE – pinch off voltage in jfet
Formulas
- D = λ / 3.14
- Cλ = (π * D) / λ
- HPBW = 52 / ( Cλ * √(N * S) )
- First Null = 115 / ( Cλ * √(N * S) )
- Gain (dB) = 10.8 + 10 * log10(N * S)
- Ae = (Glinear * λ²) / (4 * π)
Formula Explanation
CMOS PMOS NMOS (nmos pmos and cmos)
- λ: Wavelength of operation.
- N: Number of turns of the helix.
- S: Spacing between turns (in wavelengths).
- HPBW and First Null determine antenna beam characteristics.
Example
Input: λ = 0.2 m, N = 10, S = 0.25
Output: Gain ≈ 17.8 dB, HPBW ≈ 28°, D ≈ 6.37 cm
