If propagation constant is 12:60°, then the value of phase constant and attenuation constant is:

Correct Answer: α=6, β=10.39
The given propagation constant is in polar form .converting from polar form to rectangular form and equating the real and imaginary parts, we get α=6 and β=10.39.

If the attenuation due to dielectric loss and attenuation due to conductor loss in a microstrip transmission line is 0.024Np/m and 0.0724 Np/m, then the unloaded quality factor if the propagation constant is 151 is:

The propagation constant of a wave with attenuation and phase constant given by 2 and 3 respectively is

The attenuation constant causes phase distortion and the phase constant causes frequency distortion. State True/False.
