stripline_calc - Symmetric stripline transmission line analysis

SYNOPSIS

stripline_calc w h l tmet rho rough er tand f

PARAMETERS

INPUT PARAMETERS

  • w : width of stripline line (meters)
  • h : substrate thickness (meters)
  • l : lentgh of stripline line (meters)
  • tmet : metal thickness (meters)
  • rho : resistivity of the line (relative to copper)
  • rough : conductor surface roughness (meters-rms)
  • er : substrate relative permitivitty
  • tand : substrate loss tangent
  • f : analysis frequency (Hz)

OUTPUT VALUES

  • z0 : calculated characteristic impedance (Ohms)
  • elen : calculated electrical length of the line (degrees)
  • loss : calculated loss of the line (dB)
  • L : calculated inductance per length (Henries/meter)
  • R : calculated resistance per length (Ohms/meter)
  • C : calculated capacitance per length (Farads/meter)
  • G : calculated conductance per length (Siemens/meter)
  • lc : conductor loss (dB/meter)
  • ld : dielectric loss (dB/meter)
  • deltal : calculated open circuit end correction (meters)
  • depth : calculated skin depth (meters)

DESCRIPTION

Function to analyze the electrical characteristics of a single stripline transmission line. The physical dimensions of the stripline line are given as inputs and the characteristic impedance, effective dielectric constant, loss and open circuit end correction are calculated.
