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
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.
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
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.
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
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
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?
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.
Katerina, Robert - you convinced me that reading data sheets for chip antennas is good practice. Unfortunettly i have problem whith GNSS chip antennas UNICTRON H2UJ6V1A2A0100 and KYOCERA M830120 . In datasheet ground and feed are connected together. Can you explain me why? For me this is not intuitive, before this discovery i belived that real magic happend only over 10GHz
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.
@@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!
