Load and Reflection Coefficient

Question I started with

I used the RFDH Smith-chart notes to revisit reading |Γ| and phase from distance and angle with a hand calculation and my own diagram.

Load and Reflection Coefficient — concept flow — I redrew the relationships before returning to the equations.

Connecting the concepts

The key is reading |Γ| and phase from distance and angle. Before reading coordinates I record Z0, frequency, and impedance/admittance mode, then label each element or line-length move.

Equations and assumptions

I write the reference impedance, units, and linear-versus-decibel domain before substituting numbers.

Gamma = rho exp(j phi)RL = -20 log10(rho)

Worked example

For |Γ|=0.1, return loss is 20 dB.

Load and Reflection Coefficient — calculation relationship — This is my explanatory redraw, not an imported RFDH figure or a measurement result.

Connecting it to my coursework and projects

I use this order when reading my stored L-section and single-stub screens. The trajectory is an archived simulation view, not a current rerun.

What I will check next

Visual chart readings may differ slightly from calculated values. A matching answer is incomplete without normalization, wavelength direction, and open/short-stub type.
