Ansys HFSS for
Antenna Design

Course Overview

The HFSS Antenna course explores antenna-related HFSS topics such as radiating boundaries, including how well they absorb energy from different angles, and hybrid regions which connect different antenna simulations together. HFSS Antenna covers both finite element analysis (FEA) volumetric simulation as well as integral equation (IE) simulation and how they can connect a reflector antenna dish simulation to a horn antenna simulation feeding the dish. HFSS Antenna practices impedance matching antenna with circuit elements and explores examples of finite array design analysis with unit cells and Floquet modes.

Prerequisites

  • Completion of the HFSS Getting Started course or equivalent familiarity with HFSS 3D modeler, workflow, solver setup, and post-processing (plotting results graphs).
  • The HFSS 3D Components, Boundary Conditions, Ports and Mesh course is highly recommended. 
  • Knowledge of microwave electronics and antenna engineering principles, including S-parameters, transmission lines, matching networks and antenna far-field radiation patterns.

Teaching Method

Lecture slide files and hands-on simulation workshops connect technical concepts with practical skill in using HFSS FEM.  A training certificate is issued on completion of the course.

Agenda

This is a 1-day classroom course covering both tutorials and workshops. For virtual training, this course is covered over 2 x 2 hour sessions. Module 1 Introductory workshops provide antenna-related HFSS familiarity; they should be completed independently prior to the start of class.

Virtual Classroom Session 1

  • Using the HFSS Antenna Toolkit to generate antenna designs ready-to-simulate
  • Post-processing: far field plots, infinite sphere setup, S-parameter and fields plots. 
  • Near field radiation setups and plots including interaction between two horns. 
  • Overlaying field plots on antenna design geometry
  • Circulation polarization example with both lumped and wave ports. 
  • Boundaries: Radiation/ABC (absorbing boundary condition), PML (perfectly matched layer),
    and FE-BI (finite element- boundary integral)
