Formula & Theory
Resonances ≈ f, f×r, f×r², f×r³ where r is the scaling ratio.This formula is used to calculate antenna parameters for fractal antenna calculator.
Overview
Fractal Antenna helps you calculate design values for a resonant antennas project from Base Frequency, Scaling Ratio. Estimate multi-band resonances and wavelength characteristics of generic self-similar fractal antennas. Use the result to make an informed first design decision before choosing hardware, setting dimensions, or evaluating the RF system in its final environment.
Input Guide
Enter Base Frequency, Scaling Ratio exactly in the units shown by this fractal antenna. Check the operating band, unit prefix, and decimal position before calculating; these are the inputs used by the formula.
- Base Frequency — use MHz.
- Scaling Ratio.
Output Guide
The results describe the calculated fractal antenna values for the inputs you entered. Check each value against the available space, selected components, feed system, and operating conditions before making a final design decision.
How This Calculator Works
The Fractal Antenna uses Resonances ≈ f, f×r, f×r², f×r³ where r is the scaling ratio.. Supply Base Frequency (MHz), Scaling Ratio in the displayed units, then use the calculated values as the first engineering target for this resonant antennas design or analysis.
Design Notes
This resonant antennas calculation is based on Resonances ≈ f, f×r, f×r², f×r³ where r is the scaling ratio.. Real-world accuracy depends on factors such as material properties, losses, mounting, nearby conductors, ground interaction, feed-line effects, and construction tolerance. Confirm the final system with measurement or simulation.
Build and Tuning Notes
Apply the fractal antenna result as an initial target, then validate it in the intended installation. Keep the physical layout and feed arrangement consistent while testing, change one parameter at a time, and record the measured outcome before making another adjustment.
