# Ports Using Ansys HFSS — Lesson 6

Excitation methods are required for the simulation of any design. This lesson teaches excitation port assignment in HFSS. We will cover two widely used port types in this lesson — Lumped Port and Wave Port. You will learn the definition of both ports, the conditions for port assignment and the difference between both port types. This lesson also covers port assignments in two different solution types — Driven Modal and Driven Terminal. It provides insight about the integration line for both port types in driven modal solution type.

This lesson consists of one lecture and two workshops.

This lecture covers the theoretical aspects of excitation in HFSS, such as an introduction to ports, the difference between them, using a port in different solution types, integration line, etc.

### Workshop 6.1

This workshop covers the simulation aspects of Lumped Port assignment for a microstrip bend. The outline for this workshop is as follows:
open microstrip bend design >> add Lumped Ports and Open Region >> add a solution setup and frequency sweep >> simulate it >> view S parameters >> plot and animate field

### Workshop 6.2

This workshop covers the simulation aspects of the Wave Port assignment for a waveguide. The outline for this workshop is as follows:
open waveguide filter >> add wave port on both ends >> add solution setup and frequency sweep >> simulate it >> view S parameters >> plot and animate fields
