Create microstrip transmission line
Use the txlineMicrostrip
object to create a microstrip
transmission line. The cross-section of a microstrip transmission line is shown in this
figure. The physical characteristics of the microstrip transmission line include the
microstrip width (w), the microstrip thickness (t), the
substrate height (d), and the relative permittivity constant
(ε).

Properties using one or more
name-value pairs. For example, txline
= txlineMicrostrip(Name,Value)txline =
txlineMicrostrip('Width',0.0046)
creates a microstrip transmission line with
a width of 0.0046
meters.

When you set the StubMode
property to 'Shunt'
,
the 2-port network consists of a stub transmission line that you can terminate with
either a short circuit or an open circuit.
Zin is the input impedance of the shunt circuit. The ABCD-parameters for the shunt stub are calculated as:
When you set the StubMode
property to
'Series'
, the 2-port network consists of a series transmission line
that you can terminate with either a short circuit or an open circuit.
Zin is the input impedance of the series circuit. The ABCD-parameters for the series stub are calculated as:
