HFSS15: Examples of Lumped Port

Lumped ports can be used in a variety of ways as shown below.

They vary as follows:

• For 1: The 2D port rectangle touches the signal trace with one edge while the opposite edge touches the ground plane.

• For 2: The 2D port rectangle touches the signal trace with one edge while the opposite edge touches the PEC objects (drawn in grey).

• For 3: the port is an annular ring around the BGA ball where the resulting field patterns closely resemble those for a coaxial TEM mode.

Note: Use lumped ports only for those surfaces that are internal to the model and wave ports to model exterior surfaces through which a signal enters or exits the geometry.
