Conical Horn Antenna Gain Calculator | RF Aperture

The Conical Horn Antenna Gain Calculator estimates the gain of a conical horn antenna based on its dimensions and operating frequency. Horn antennas are valued for wide bandwidth and directional radiation.

EXAMPLE:

• INPUTS:

  • Conical Horn Antenna Operating Frequency = 10 GHz
  • Conical Antenna Aperture Diameter = 0.2 meters
  • Efficiency of Antenna = 0.51

• OUTPUT:

  • Conical Horn Antenna Gain = 23.5 dBi
