Attenuation Constant & Phase Constant Calculator

When electromagnetic waves propagate through transmission lines, they experience attenuation and phase shift. These effects are quantified using attenuation constant and phase constant, which are crucial for analyzing signal loss and phase behavior in RF and microwave systems.

EXAMPLE:

• INPUTS:

  • Operating Frequency (GHz) = 1
  • Permeability (Free Space) (H/m) = 4 _ π _ 10^-7 = 1.257E-6
  • Permittivity (Free Space) (F/m) = 8.854 x 10^-12 = 8.854E-12
  • Conductivity (S/m) = 0.01

• OUTPUTS:

  • Attenuation Constant (α) = 1.88 Neper/meter
  • Phase Constant (β) = 21.04 radian/meter
