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 helps you calculate design values for a wireless communication project from Transmit Power, Magnetic Coupling, System Efficiency. Estimate received power, efficiency, power loss, and RF power level for a wireless power transfer (WPT) system using coupling and system efficiency. 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 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
This wireless communication calculation is based on Pout = Pin × (Coupling/100) × (Efficiency/100). 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 wireless power transfer 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.
