Question

Difference between wave port and lumped port excitstion

Answer 1

hope my answer helps u

Answer 2

I would use only lumped ports when using wave ports are not possible. Wave ports use a 2D solver on the port cross-section to obtain the modes that will propagate down a transmission line of infinite extent. They can be used for many geometries such as waveguides, stripline, CPW, microstrip, coax, etc.

Lumped ports can be used to feed balanced antennas such as dipoles or spirals. They can also be used when geometries are constrained so that the port must be internal to the problem.
