You're doing a great work Mr. Feranec and still such a simple and humble person. Thank you for just being you and sharing us this great content from industry experts.

Robert, you are SUCH a value to the thousands of young (and not young) people! You are bringing the knowledge FOR FREE to the masses! You DON'T present yourself (unlike 99% of YTbers) but you bring the knowledge, usually by means of experts in the particular field! UNBELIEVABLE and chapeau bas

[@Scuba_Bro]

I spend all day at work looking at HFSS and immediately at the start of the video I see it again 😂 what is wrong with me lol great video and great explanation. I agree with almost everything she said.

[@katerinagalitskaya8948]

Its never too much with HFSS 😂

[@alessandrocagliostro8599]

It was a pleasure meeting you at embedded world! I had a blast talking to you. Keep up the good work! :)

[@philorkill]

Very informative. Thank you for sharing your knowledge.

[@biswajit681]

Robert please bring SMPS magnetics design expert on your channel and possibly if you could bring any training course that would be really great... because very less or almost no resources are available over the internet And another topic is EMC design simulation and modelling using Ansys or similar tools

[@arenaengineering8070]

Thanks fo the lecture.

[@TheEmbeddedHobbyist]

if they are harmonically related then one track might be able to do both, otherwise you will need I expect two different length tracks. each one will become resonant without affecting the other much so giving you 50 Ohms at each band.

[@katerinagalitskaya8948]

Do you mean feed line? If calculated correctly there is no problem to use one feed for multiband antennas

[@TheEmbeddedHobbyist]

yes, I often use one feed line to parallel antenna's as long as the resonances are far enough apart not to affect each other. @@katerinagalitskaya8948

[@torique6250]

Hi! Thank you for a very infomative video! I would like to ask to the Radiation Efficiency tables were obtained in HFSS? Thank you!

[@katerinagalitskaya8948]

Do you mean how to get that efficiency data in HFSS? You go to reports->antenna parameters->radiated efficiency

[@gcaricato]

Good job, Katerina! May I ask how you usually model copper traces/planes? Do you create sheets and then apply PEC boundary or do you create 3D geometry (in order to have some thickness) and then apply copper material? Do you get almost the same results?

[@katerinagalitskaya8948]

When working with small models (single elements) it is always the best details the better. Thickness to copper, no perfect boundaries. When we want to tune S parameters, it is especially important (not so much when we care only about radiation patterns). The higher in frequency you go the more important it is to have copper thickness and roughness defined. When we work with big models (multi-element arrays) it is possible to simplify model to sheets in order to have less heavy simulation.

[@ChrisJackson-js8rd]

ansys looks impressive. are there any good free or cheap antenna simulators?

[@katerinagalitskaya8948]

I have seen one called OpenEMC, you can find it on google

[@TheEmbeddedHobbyist]

I always find it funny when folk want gain from an omnidirectional antenna. 🙂

[@katerinagalitskaya8948]

Indeed! But we usually want to have at least a bit of gain :)

[@TheEmbeddedHobbyist]

ha but what you gain on the swings you lose on the roundabouts. in other words directivity comes with gain so you lose gain in some direction. As long as that direction is ok then good to go. with a phone losing some high angle radiation and gaining on the low angle may help as mobile phone masts are normally quite close to the ground as far as angle of radiation is concerned. great video by the way. @@katerinagalitskaya8948

[@TheDutchGuyOnYT]

As compared to an isotropic antenna?

[@TheEmbeddedHobbyist]

Is that the not the base on which we normally base any gain. or the difference in forward gain from one to another. but in isolation it's normally gain over an isotropic radiator. (dBi) @@TheDutchGuyOnYT

[@katerinagalitskaya8948]

@@TheDutchGuyOnYT yes, conpared to 0dbi

[@miguelangellopezdibenedett9783]

I wonder what we will be able to simulate in a few years...

[@NOW-IS]

The problem is always, that many manufacturer dont provide simulation files and also simulation software is not really available for many people.

[@katerinagalitskaya8948]

Every reliable chip antenna manufacturer will provide data about reference board. How antenna will work on a different board will not be provided and that is a challenge to estimate without simulation.

[@NOW-IS]

@@katerinagalitskaya8948 thanks for your reply. I want to correct my comment. This video already helped a lot and. I meant it is hard to get a starting point into the whole antenna simulation topic. I have many ongoing designs where it would really save time and money if I could do that on my own. To be honest I am a beginner in this topic. But I am eager to learn more about it and would like to play arround with the some simulation software. But where to start? I am open for anything :) Maybe I just use the wrong sources for it. In general I think there is a high need for providing some beginner tutorials into that topic. Maybe it is also related to the fact that the antenna engineering field is really difficult to understand and not easy to learn or I am just stupid :D Thanks for your work and sharing your knowledge. Keep on!
