mstripa

microstrip analysis (calculates Z,eff from w/h)

Calling Sequence

[eff,Z] = mstripa(er,u)

Parameters

er

relative permittivity of substrate

u

width-to-height ratio = w/h

eff

effective permittivity

Z

characteristic impedance of line

Description

mstripa(er,u) performs microstrip analysis (calculates Z,eff from w/h)

velocity factor = 1/sqrt(eff) can calculate a vector of Z's and eff's from a vector of u's. uses Hammerstad and Jensen emprical formulas. accuracy is better than 0.2% over u=(0.01,100) and er less than 128

Examples
