Accurate Antenna Simulations, but Demands High Resources **Rating:** 4.0/5.0 stars **Reviewed by:** Abhishek B. | RF engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** May 27, 2026 **What do you like best about Ansys HFSS?** I like Ansys HFSS for its accuracy and reliability in electromagnetic and antenna simulations, especially for product-level analysis. HFSS helps me understand how an antenna behaves in real-world conditions when integrated inside an enclosure or complete device. The radiation pattern, gain, efficiency, and impedance matching results are very close to practical measurements, which helps reduce prototype iterations and development time. **What do you dislike about Ansys HFSS?** One area where Ansys HFSS could improve is the simulation time and computational requirements for large product-level models. When simulating complete devices with multiple antennas, shielding structures, and detailed components, the simulation can become very time-consuming and requires high-end system resources such as large RAM and powerful processors. Another challenge is the meshing process for complex geometries. Sometimes achieving proper mesh convergence takes multiple iterations and manual tuning, especially for electrically small structures or very detailed models. This can increase overall development time. **What problems is Ansys HFSS solving and how is that benefiting you?** I use Ansys HFSS for accurate and reliable antenna simulations, which helps me understand real-world behavior and reduce prototype iterations, saving development time. ### 2.

For my project I was able to create a unique model of planar antenna was able to simulate the find out the S parameters for the different changes I have made in the design. **What do you dislike about Ansys HFSS?** Ram usage, while doing the simulation I have faced lot of crashes in between. And also when I was simulating the same design on two different computers I was able to see few mismatches in the results. And I was able to create different designs, and in my designs I had to make a lot of slits in for my antenna as a part of my research but for that each time I had to insert an another slit shaped object and had to do the subtraction for getting the slit. At that time I felt the need of an extra tool that can be used to cut out the shapes we needed for the main design. **What problems is Ansys HFSS solving and how is that benefiting you?** I have used Ansys for creating planar antenna and get the transmission parameters for the antenna for different design specification and also i have implemented waveguids etc. I have created different design of planar patch antenna with different grounds. Such as i have used circular ground shape , triangle ground shape pentagon shaped ground etc in my design. And also I did few research on putting defects in the ground will affect the transmission coefficient. I was able to see shift in S Parameters for the defects in ground. ### 9. User Friendliest EM Simulator **Rating:** 5.0/5.0 stars **Reviewed by:** Hossein B. | Research Assistant, Enterprise (> 1000 emp.) **Reviewed Date:** December 01, 2020 **What do you like best about Ansys HFSS?** Creating the structure and apply boundary condition is very easy and straightforward. It has a project tree that I like it very much and also meshing is very good although not the best. **What do you dislike about Ansys HFSS?** It can provide more examples and a better website for some sample simulations. It can also be updated with more boundary conditions and especially more excitation methods like dipole source excitation. It would also be nice if ansys could investigate more in optical simulations as well as EM in microwave domain. Plus, it can introduce a programming part not the one with matlab but an easy one like the way numerical does. **What problems is Ansys HFSS solving and how is that benefiting you?** I usually work with problems that are in the area of the microwave antenna and microwave cavity design. These problems can be versatile with a lot of applications in quantum cavity electrodynamics. Simulation of the magnetic field with its counterpart called Maxwell is usually done by me. ### 10. Know if you will succeed or not **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Oil & Energy | Small-Business (50 or fewer emp.) **Reviewed Date:** September 23, 2021 **What do you like best about Ansys HFSS?** I like that I was able to perform analysis on my designs while still in the conceptual stages so I didn't waste time on a design with structural weaknesses. **What do you dislike about Ansys HFSS?** I thought it was rather cumbersome to set up and get going at first but after some time you get used to it. **What problems is Ansys HFSS solving and how is that benefiting you?** I was solving the problems of structural failures before they happen. ### 11. Best Simulator for Antenna Design - Hands Down! **Rating:** 4.5/5.0 stars **Reviewed by:** Imran A. | Area Manager (Retail Sales), Enterprise (> 1000 emp.) **Reviewed Date:** January 02, 2021 **What do you like best about Ansys HFSS?** Highly accurate for closed field design in fact it had been the best solution our research group had at our disposal for the analysis of three-dimensional electromagnetic field analysis. **What do you dislike about Ansys HFSS?** Computation speed can be a little slow but that could also be a function of the user's system but HFSS, overall, is a bit heavy in the use of system resources. **What problems is Ansys HFSS solving and how is that benefiting you?** I was involved in research projects where we were required to design antennas which would later be used in satellite communications by a top research group of the country where our role was to work with the provided specifications but optimise them to achieve the desired gain which required a lot of highly accurate simulations otherwise the costs would've been highly prohibitive and that's where HFSS helped us in delivering what was expected of us while staying within the allocated budget. The end result was that we only fabricated the most efficient antenna was found on the basis of our HFSS simulations and the final practical results were extremely close to the simulated ones provided by HFSS. ### 12. Accurate software for EM simulation, wide range of simulation schemes and a great customer support. **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Automotive | Small-Business (50 or fewer emp.) **Reviewed Date:** November 25, 2020 **What do you like best about Ansys HFSS?** 1- After fabrication of the product you would get very accurate results quite similar to what you had simulated. It is extremely accurate. 2- Wide range of simulation and post processings which makes it easier to get what you need. 3- Integrity of the products, you have access to the different simulator for different purposes while they would easily communicate with each other which make it faster get the design done. 4- Cloud computing, offering simulation on HPC make the simulations quite fast while you do not need to worry about the server maintenance. **What do you dislike about Ansys HFSS?** 1- Setting up cloud computing (HPC) required a bit of IT knowledge and is not straight forward. 2- It's hard to work with complex meshes in HFSS. The user 3D interactions and the tools need to be improved. 3- Again related to the 3D environment it is hard to draw an object quickly and accurately take a lot of time for developing a model. **Recommendations to others considering Ansys HFSS:** Love this SW for EM simulations. **What problems is Ansys HFSS solving and how is that benefiting you?** I am doing EM simulations and antenna design. Benefits: - Accuracy - Optimiser tool - Variety of available post-processing options ### 13.

EM Simulation with HFSS **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Defense & Space | Enterprise (> 1000 emp.) **Reviewed Date:** December 01, 2020 **What do you like best about Ansys HFSS?** Most helpful feature is the debugging tools integrated into the software. A validation check will return all the errors in your design with useful tips of how to fix them. Also, their support team is always an email away to get any other issues fixed! **What do you dislike about Ansys HFSS?** The programme files are not backwards compatible. If you create a design on HFSS 2017, you cannot open it on a 2019!! This has led to some issues throughout my team. **Recommendations to others considering Ansys HFSS:** Highly recommend the product especially with the new crossover feature allowing the same design to be used in ICEPACK and thermal simulations and then with HFSS the EM simulation. This allows ease of editing the designing and measuring different effects. **What problems is Ansys HFSS solving and how is that benefiting you?** EM simulations. Typically antenna design and PCB layouts of antenna feeds. Great optimisation and tuning features when parameterising variables correctly. This speeds up simulation time significantly. Also being able to run Python scripts through HFSS speeds up post processing and data exports. ### 16. Powerful software marred by many annoyances and questionable stability **Rating:** 3.5/5.0 stars **Reviewed by:** Verified User in Wireless | Enterprise (> 1000 emp.) **Reviewed Date:** November 27, 2020 **What do you like best about Ansys HFSS?** I like the software's accuracy and the modeler is okay. One major pro is that if I copy and paste a solid from one project to another, I can go into the solid and still alter its dimensions. In other softwares, once you copy and paste, you can no longer edit to solid. In general, though, HFSS presents results I can trust, even if getting them can be irritating sometimes. **What do you dislike about Ansys HFSS?** HFSS had stability problems when I was using it. I don't know if it was a hardware issue, but crashes weren't as much of a rarity as I would have liked. It's not the most unstable software I have used (that title goes to Altium), but more than once, I lost a good amount of work due to a crash mid-simulation. Furthermore HFSS erases the ability to undo model alterations after a simulation has begun. The software I use most frequently nowadays is CST Microwave Studio, which keeps track of all your actions in a history list. The downside to that is the more you work on a model, the longer it takes to update the history list after an edit is made, which is unfavorable. However, I would rather have the ability to undo at all after a simulation, especially if I change something that is not based on a parameter variable. Aside from that, the thing about HFSS that I dislike the most is the presence of a certain error that would appear randomly but periodically across projects and what I had to do to get rid of it was never consistent (increasing my airbox size by a random amount, no matter how small, was even a solution sometimes). Unfortunately, I do not remember the text of the error (I apologize for how unhelpful that is), but it had something to do with the meshing I think and the error message was not specific. I do not think it was user error because, again, the cause and solution were never consistent. I think the modeler needs work as well; CST has the option to define coordinate system positions based on model vertices, edges, and faces. This makes building models far more efficient. HFSS should adopt similar techniques. Further, I would really love the ability to extrude shapes off of the faces model objects. **Recommendations to others considering Ansys HFSS:** This software will work for you, but it is not without its headaches. I believe it is more accurate and versatile than CST Microwave Studio, but CST is faster in terms of modeling and simulation. **What problems is Ansys HFSS solving and how is that benefiting you?** Filter and cavity design mostly with some antenna simulations. Again, taking HFSS designs into fabrication carries over pretty well. ### 17.

The simulated results obtained from HFSS were quite close to the experimental results obtained in the lab. We can even customize the simulation time according to what level of accuracy is acceptable in a particular application. **What do you dislike about Ansys HFSS?** The simulation time is very large and depending upon the complexity and accuracy required it increases even more. Therefore, making changes in the structure (to get to perfect) and re simulate is a really time-consuming process. **What problems is Ansys HFSS solving and how is that benefiting you?** Worked on design and analysis of a dual-band Wilkinson power divider. Created a 3-D model of the structure and simulated it before making it to fabricate. ### 21.
