1.6.4    Drawing the ports

In this step we need to draw and define the ports. In this case we need to define two ports, input and output with TEM mode excitation.

To define the ports we need to go to Model tab. As a first one, we will define the transmission line input port. For that purpose we press Transmission Line  commands button and choose Insert Transmission Line Source  command.

The following dialogue will appear.

We set the name of the port to SourcePort. The default Type, Activity and Orientation of the port are properly set for this case. Full Plane option sets the port dimensions equal to the bounding dimensions of the entire project in the directions perpendicular to the port orientation what is suitable in this case. We uncheck the Reference option – it is not necessary since we do not calculate S-Parameters.

In the Parameters tab we set sinusoidal excitation at 5GHz. We excite the structure with a fundamental TEM mode. Pressing OK button accepts the settings.

Now press Transmission Line  commands button and choose Insert Transmission Line Load  command.

The following dialogue will appear.

We set the name of the port to LoadPort. The default Type and Orientation of the port are properly set for this case. We should change Activity to MINUS (please note that when Full Plane option is checked, port will change its position to the opposite side of the project). We uncheck the Reference option – it is not necessary since we do not calculate S-Parameters.

In the Parameters tab we set sinusoidal excitation at 5GHz. We excite the structure with a fundamental TEM mode Pressing OK button accepts the settings.

The LoadPort can be also set by creating a copy of SourcePort and changing its parameters.

Previous step: Drawing the structure.

Next step: Setting boundary conditions.
