Homework 7 - Microstrip Lines
Problem 5.
Given a microstrip line with a ratio of line width to substrate thickness is w/h = 3.50,
and the relative permittivity of the substrate material is 9.0. Calculate the following:
a) The characteristic impedance of the line
b) The effective relative permeability
c) The wavelength on the line for a frequency of 3GHz
{ Solution }
Problem 7.
For this question, repeat Problem 5 for a width and height ratio of w/h = 1.0.
{ Solution }
Problem 8.
A 10ohm microstrip line is to be constructed on an alumina substrate having a relative
permittivity of 9.0. Determine the required ratio of w/h and the effective relative permeability.
{ Solution }
Problem 9.
For this question, repeat Problem 8 but for a 75ohm line.
