Constructing a Microstrip Line
Create a twoport 50 Ohm microstrip line using a planar multilayer substrate in CADFEKO.

Design a 50 Ohm microstrip line on a substrate of height 0.787 mm and
permittivity of 2.33, using one of the following methods:
 Use a thirdparty tool (transmission line calculator) to calculate the dimensions of the microstrip line.
 Calculate the dimensions of the microstrip line using equations from literature.

Create the microstrip line in CADFEKO using the
dimensions obtained in Step 1.
Tip: Use a planar multilayer substrate for the dielectric layer and ground plane.

To ensure finer meshing along the length of the microstrip line:

Copy the side edges and translate the edges a distance of 1/7 of the
microstrip line width.
 Define a local mesh refinement on the two translated edges.

Copy the side edges and translate the edges a distance of 1/7 of the
microstrip line width.
