Formula & Theory
λ₀ = c / f | Effective Wavelength λ_eff = λ₀ · VF | Monopole L = (λ₀ · VF) / 4This formula is used to calculate antenna parameters for smart meter antenna calculator.
Overview
Smart Meter Antenna Calculator supports wireless communication planning with a practical calculation based on the displayed inputs.
Input Guide
Enter Operating Frequency, Antenna Medium & Substrate, Custom Velocity / Shortening Factor (VF or K) exactly in the units shown by this smart meter antenna. Check the operating band, unit prefix, and decimal position before calculating; these are the inputs used by the formula.
- Operating Frequency — use MHz.
- Antenna Medium & Substrate.
- Custom Velocity / Shortening Factor (VF or K).
Output Guide
The results describe the calculated smart meter 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 Smart Meter Antenna uses λ₀ = c / f | Effective Wavelength λ_eff = λ₀ · VF | Monopole L = (λ₀ · VF) / 4. Supply Operating Frequency (MHz), Antenna Medium & Substrate, Custom Velocity / Shortening Factor (VF or K) in the displayed units, then use the calculated values as the first engineering target for this wireless communication design or analysis.
Design Notes
Installed performance can vary with frequency, losses, tolerances, environment, and system configuration.
Build and Tuning Notes
Use the result as a starting point, then validate the completed system with measurement or simulation.
