Input impedance for quarter wave and half wave transmission line

  1. Input impedance Zi for quarter wave transmission line

A transmission line is said to be quarter wave transmission line when its length equals quarter wavelength.

That is                                             l=λ/4

Or                                                   l=(2n-1)λ/4 (odd multiple of λ/4)

Or                                                   βl=2π/λ * λ/4                                              [ β=2π/λ]

=π/2 Continue reading “Input impedance for quarter wave and half wave transmission line”
