Antenna Design With HFSS

 
Ansys 3D High Frequency Simulation Software (HFSS) is a widely used electromagnetic simulation software to model antennas, antenna arrays and other electromagnetic and radio frequency components. It uses finite element methods (FEM) as the solver. In the following worksheets, you will find step-by-step guidance on modelling different types of antennas, how to adjust the various parameters such as the radiation space, conductive and non-conductive boundaries, and the analysis set-up. The worksheets start from modelling a quarter-wave monopole antenna over a ground plane with gradually increasing complexity until the microstrip patch antenna. Every worksheet guides you through the entire process therefore the user has the flexibility to refer only to the particular antenna modelling worksheet without going through the entire set. These are designed for an audience of senior undergraduate students and entry-level graduate students and no prior experience in electromagnetic modelling is needed to complete the tasks. Hope you enjoy this learning experience!

  • Worksheet 01 - Monopole by Ashanthi Maxworth PhD

    Worksheet 01 - Monopole

    Ashanthi Maxworth PhD

    This worksheet guides users on modeling a quarter-wavelength monopole antenna on an infinite ground plane and observing its characteristics. The worksheet starts with parameter settings and continues on to antenna design, boundary setting, radiation setting, and then to simulation and viewing the results.

  • Worksheet 02 - Meshing by Ashanthi Maxworth PhD

    Worksheet 02 - Meshing

    Ashanthi Maxworth PhD

    This worksheet is designed to oberserve the variations in results when the mesh is varied from coarse to fine, hence how to find the optimum mesh size such that we can get accurate results while not compromising computational power.

  • Worksheet 03 - Near field by Ashanthi Maxworth PhD

    Worksheet 03 - Near field

    Ashanthi Maxworth PhD

    This worksheet guides students to change the observational region between, reactive near field, radiating near field, and far-field.

  • Worksheet 04 - Dipole by Ashanthi Maxworth PhD

    Worksheet 04 - Dipole

    Ashanthi Maxworth PhD

    This worksheet shows how to create a half-wavelength dipole, set the feeder through a port, observe directivity, half-power beamwidth, etc.

  • Worksheet 05 - Loop by Ashanthi Maxworth PhD

    Worksheet 05 - Loop

    Ashanthi Maxworth PhD

    In this worksheet, the users can design a small loop. The small loop shows low directivity, hence at the end of the worksheet, the users can chanage the design parameters and increase the directivity.

  • Worksheet 06 - Arrays by Ashanthi Maxworth PhD

    Worksheet 06 - Arrays

    Ashanthi Maxworth PhD

    This worksheet designs an antenna array with three identical dipole elemetns. The antenna is operating as a broadside array. By changing the parameters the users can view the grating lobes in addition to the main lobe.

  • Worksheet 07 - Bicone by Ashanthi Maxworth PhD

    Worksheet 07 - Bicone

    Ashanthi Maxworth PhD

    In this worksheet, setps are given to design a full-wavelength biconical antenna. This is a broadband antenna. The worksheet also shows how to observe surface currents.

  • Worksheet 08 - Helix by Ashanthi Maxworth PhD

    Worksheet 08 - Helix

    Ashanthi Maxworth PhD

    This worksheet creates a helical antenna operating in the axial mode. The antenna is mounted on a ground plane. The users can change the circumference of the helix and change the operating mode to broadside or conical if they wish.

  • Worksheet 09 Horn by Ashanthi Maxworth PhD

    Worksheet 09 Horn

    Ashanthi Maxworth PhD

    This worksheet designs a pyramidal horn antenna fed by a waveport.

  • Worksheet 10 - Patch by Ashanthi Maxworth PhD

    Worksheet 10 - Patch

    Ashanthi Maxworth PhD

    In this worksheet, steps are given to create a slotted rectangular microstrip patch antenna with an inset feed using a stripline. The patch antenna is operating in the TM10 mode.
