Gain (dB): --

Directivity (dB): --

Beamwidth (degrees): --

Calculation Formula

Gain (dB) = 10 * log10(Gain)

Directivity (dB) = 10 * log10(Directivity)

Where:
Gain = (4π / λ) * (width * height)
Directivity = Gain
Beamwidth = 140 / width (in degrees)

How to Use the Horn Antenna Calculator

The Horn Antenna Calculator is designed to calculate the gain, directivity, and beamwidth of a horn antenna based on its dimensions and operating frequency.

  1. Enter the operating frequency of the horn antenna in GHz.
  2. Enter the width of the horn antenna in cm.
  3. Enter the height of the horn antenna in cm.
  4. Click the "Calculate" button to compute the gain, directivity, and beamwidth.
  5. Use the "Reset" button to clear all input fields and results.

Working Principle

The gain of a horn antenna is determined by its dimensions and the operating frequency. The directivity is closely related to the gain, and the beamwidth is inversely proportional to the width of the horn.

The formulas used for the calculations are:

  • Gain (G) = (4π / λ) * (width * height)
  • Directivity (D) = Gain
  • Beamwidth (θ) = 140 / width

Where λ is the wavelength of the operating frequency.
