PT Card

This card defines a port connected to the full wave model. Reference this port when defining sources, loads, networks and transmission lines.

In the Source/load tab, in the Ports group, click the  Port (PT) icon.

Parameters

Wire segment port
Add port to segment with label
Specifies the segment label where the port is placed.
Reverse port orientation
Select this option if the polarity of the port is to be reversed.
Wire vertex port
Add port to segment with label
Specifies the segment label where the port is placed. The port has to be located at a node, either between two segments, or between a segment and a triangle, ground plane or polygonal plate.
Port at start of segment
Select this option if the port location is at the start of the wire segment with a matching label.
Point at end of segment
Select this option if the port location is at the end of the wire segment with a matching label.
Use default feed direction (like basis functions)
If this option is selected, the positive feed direction is consistent with the basis function setup. For wire/surface junctions (UTD plates, infinite planes with the BO ground, or meshed triangle surfaces), this direction is away from the wire onto the surface. For wire connections between two segments, this direction is from the segment with the lower index to the segment with the higher index.
Positive feed direction like wire segment orientation
If this option is set, then the positive feed direction is like the orientation of the wire segment with the specified label
Negative feed direction like wire segment orientation
If this option is set, the negative feed direction is opposite to the orientation of the wire segment with the specified label.
Edge port
Edge port between regions with multiple labels
The edge port is placed on the edge between the regions with labels specified in Negative side and Positive side. The positive source direction is from the Negative side towards the Positive side. Use the field Maximum number of labels on a side to increase the number of rows available in the table.
Edge port connected to ground/UTD

The edge port is placed on the edges of metallic triangles with the labels specified in the Negative side or Positive side. The edges of these triangles are connected to UTD surfaces or to a PEC ground plane (as specified with a BO or GF card).

Edge port of microstrip between two points
The edge port is placed on all edges on a line between points (previously specified with DP cards). The points are specified in the Start point of edge and End point of edge dialogs. A GF card with a conducting ground must be present.
Meshed surface represents positive feed side
By default, the feed direction is such that the meshed surface represents the negative feed side. The vector direction of the current is then towards the UTD or ground. When this option is checked, the feed orientation is reversed.
Line port (FEM)
Coordinates of the start and end points in the model unit.
