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. 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. ### 3. 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. ### 4. Using HFSS for patch antenna design was a blast, its easy to use and very easy to learn **Rating:** 4.0/5.0 stars **Reviewed by:** Bara'a S. | RF Engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** November 26, 2020 **What do you like best about Ansys HFSS?** Very easy to use and I learned how to use it in no time, it's pretty accurate with respect to other simulation tools. **What do you dislike about Ansys HFSS?** There should be more user guides or maybe more in detail official tutorial. Errors are not that easy to identify **Recommendations to others considering Ansys HFSS:** HFSS is a great tool to simulate rf components and Antennas, it can be learned very quickly and it's easy to use, just be sure its what you need. **What problems is Ansys HFSS solving and how is that benefiting you?** Simulating patch antenna and it works very good, the simulation results are always very close to the expectations. ### 5. Excellent simulator for electromagnetic structures **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Higher Education | Small-Business (50 or fewer emp.) **Reviewed Date:** November 25, 2020 **What do you like best about Ansys HFSS?** The tool provides us with an environment that enables us to draw the actual high-frequency structure based on requirements and applications. 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. ### 6.

The best tool for electromagnetics analysis **Rating:** 4.0/5.0 stars **Reviewed by:** Mohammadreza R. | Small-Business (50 or fewer emp.) **Reviewed Date:** October 17, 2018 **What do you like best about Ansys HFSS?** Its user-friendly feature is one of the best features. You can draw what in your mind is and do your simulations. I bet it is the best software in terms of accuracy as I compared its results with measurements and they were perfectly matched. Students can take advantage of the student version from this link:https://www.ansys.com/academic/free-student-products If you look at the publications in IEEE Transaction on Antenna and Propagation, you can find out that authors mostly use HFSS for their simulations. **What do you dislike about Ansys HFSS?** Probably defining the boundary conditions is a little complicated and needs experiences to set the correct one with correct dimensions. Its documentation is far behind the abilities of the software. Probably defining the boundary conditions is a little complicated and needs experiences to set the correct one with correct dimensions. Its documentation is far behind the abilities of the software. **Recommendations to others considering Ansys HFSS:** Nowadays in antenna and microwave design, there are two big software, HFSS, and CST. As an engineer who used both in an advanced level, I prefer HFSS as it is more versatile in drawing and design. **What problems is Ansys HFSS solving and how is that benefiting you?** In my previous project, I was antenna and RF designer. So I used HFSS for designing and simulating different antennas and antenna arrays. In my previous project, I was antenna and RF designer.
