Antenna Effective Area Calculator

Calculate antenna effective aperture (Ae) from gain and frequency using the formula Ae = (G × λ²) / (4π). Shows wavelength, effective area in m² and cm², and estimated physical aperture.

How to Use Antenna Effective Area Calculator

Enter the operating frequency and select the unit (MHz or GHz). Enter the antenna gain in dBi. Click Calculate to get the effective area, wavelength, and estimated physical aperture diameter.

Step-by-Step Instructions

  1. Enter operating frequency (MHz or GHz)
  2. Enter antenna gain in dBi
  3. Click Calculate Effective Area
  4. View effective area and physical aperture estimate
