Example20 Balanced Line(Coupled Line) without Connector

General

Item	Settings
Solvers	Electromagnetic Analysis [Hertz]
Analysis Type	Harmonic analysis
Options	Select “Ignore the influence of face/edge electrode thickness” *

* This is the default setting. There are no face electrodes with this model. Therefore it is irrelevant to select it or not.

The harmonic analysis is set up as follows.

Tab	Setting Item	Settings
Mesh Tab	Frequency-Dependent Meshing	Reference frequency: 1×10^9[Hz] Select “The conductor bodies thicker than the skin depth constitute the boundary condition.”
Harmonic analysis	Frequency	Minimum: 0.15×10^9[Hz] Maximum: 1.5×10^9[Hz]
	Sweep Type	Select Linear step Division number: 5
	Sweep Setting	Select discrete sweep

Two microstrip lines are placed in parallel. Port 1 and Port 2 are on the same face.

Create a face which includes ports, and set the “I/P Port” there. This face doesn’t need to have either the material name or the body attribute name.

Electric wall surrounds the model. The boundaries of Port1 and Port2 are treated as electric wall too.
