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
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
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
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
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
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
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
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
Ashanthi Maxworth PhD
This worksheet designs a pyramidal horn antenna fed by a waveport.
-
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.
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!
