Antenna Efficiency Calculator

This calculator helps determine the efficiency of an antenna by comparing its radiated power to its input power. Antenna efficiency is a critical metric in wireless communication systems, as it indicates how effectively an antenna converts input power into radiated electromagnetic waves.

Key Features:

• Calculates antenna efficiency as a percentage.
• Helps optimize antenna design for better performance.
• Useful for engineers, hobbyists, and students in RF and telecommunications.

How to Use:

1. Enter the radiated power (in watts) from the antenna.
2. Enter the input power (in watts) supplied to the antenna.
3. Click "Calculate" to get the efficiency percentage.

Example Calculation:

Important Notes:

• Efficiency is always ≤ 100% due to inherent losses.
• Factors like impedance mismatch and material losses affect efficiency.
• Higher efficiency antennas provide better signal strength and range.

Applications:

This calculator is useful for designing antennas for Wi-Fi, cellular networks, satellite communication, and amateur radio. It helps identify inefficiencies and guides improvements in antenna construction and tuning.
