Formula & Theory
Pout = Pin × (Coupling/100) × (Efficiency/100)This formula is used to calculate antenna parameters for wireless power transfer calculator.
Overview
Wireless Power Transfer Calculator supports wireless communication planning with a practical calculation based on the displayed inputs.
Input Guide
Enter Transmit Power, Magnetic Coupling, System Efficiency exactly in the units shown by this wireless power transfer. Check the operating band, unit prefix, and decimal position before calculating; these are the inputs used by the formula.
- Transmit Power — use W.
- Magnetic Coupling — use %.
- System Efficiency — use %.
Output Guide
The results describe the calculated wireless power transfer 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 Wireless Power Transfer uses Pout = Pin × (Coupling/100) × (Efficiency/100). Supply Transmit Power (W), Magnetic Coupling (%), System Efficiency (%) 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.
