Formula & Theory
λeff = λ / √εrThis formula is used to calculate antenna parameters for wearable antenna calculator.
Overview
Wearable Antenna helps you calculate design values for a microstrip & printed antennas project from Frequency, Fabric Dielectric Constant (εr). Calculate wavelength and approximate wearable antenna dimensions for textile substrates. 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 Frequency, Fabric Dielectric Constant (εr) exactly in the units shown by this wearable antenna. Check the operating band, unit prefix, and decimal position before calculating; these are the inputs used by the formula.
- Frequency — use GHz.
- Fabric Dielectric Constant (εr).
Output Guide
The results describe the calculated wearable 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 Wearable Antenna uses λeff = λ / √εr. Supply Frequency (GHz), Fabric Dielectric Constant (εr) in the displayed units, then use the calculated values as the first engineering target for this microstrip & printed antennas design or analysis.
Design Notes
This microstrip & printed antennas calculation is based on λeff = λ / √εr. 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 wearable 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.
