Hello, i am in 2nd year of my PhD and pursuing electronic engineering. I am doing research on the topic frequency selective surfaces: Analysis and Design. I need to design DRA and i am in a huge dilemma regarding which software i should use? Should i use HFSS, CST?
I am not at all clear about both of them and i need some assistance ASAP. As i have to submit my research to my supervisor after 1 week.
Pls help!

Hey, Actually, it depends on your proficiency over particular software. Both of the techniques can be considered appropriate for designing DRA. You just need to be clear with your thoughts about both the software. DRA simulation for both software is very easy. HFSS is based on Finite Element Method (FEM) which is more accurate for designing antennas while CST is based upon Finite Integration in Technique (FIT) and is also popular among antenna designers due to ease in simulations. However, results of both the simulators are not same because of different computational techniques involved.
If i need to suggest you one of these, i would recommend you to use CST. It is better as it is fast and saves your time and also, easy to do. I have designed one (DRA) on it. It is superior also
I think my suggestion must have helped you.

I agree and would also suggest you use CST rather than using HFSS. As CST is obviously better, it is time-saving and more accurate.
CST microwave studio is a fast and user-friendly code for DRA. I used the same method that’s why i am so confident about the technique. I used it for powerful for Helicon antenna design and simulation.

Read the link above, it has a detail about both os the techniques and also about the difference between them. In my opinion, if you would understand the difference between them then only you would be able to design DRA.
