Effective Antenna Aperture Calculator
Calculate the effective aperture using:
\[
A_e = \frac{\lambda^2\,G}{4\pi}
\]
with \(\lambda=\frac{0.3}{f}\) (m) for frequency \(f\) in GHz and \(G=10^{\frac{G_{\rm dB}}{10}}\).
* Enter the operating frequency (GHz) and antenna gain (dB).
Step 1: Enter Parameters
Example: 10 GHz
Example: 20 dB
