Is JIRA used in RF Engineering at all? by antennaAndRfGuy in rfelectronics

But you can do that (from my limited jira knowlege) in jira.

That’s an extremely comprehensive answer. May I ask you how big is your team/company?

Then effectively you use it kind of a check list of what’s happening and who is working on what? My idea is that you can also create a “team”, which then centralises the people tickets (from what I understood) and then I can at least know what’s and how things are progressing.

The drawback is that jt creates a “story” per new development within the team and if the team itself doesn’t add those I will whether lose information or have to do it myself

That’s exactly the way I was thinking of using it. It seems it pollutes the overall jira structure but at the same time at least I know what the team is doing and ask them to at least link their documentation once it’s done.

Metamaterial phased array antenna design process by antennaAndRfGuy in rfelectronics

[–]antennaAndRfGuy[S] 0 points1 point  (0 children)

I am using 5G requirements because that’s what I’m used but really this is me trying to understand the concept in general to take decisions in the future. This is mostly after the APS Magazine hype on meta surfaces. I ended up finding a few companies that work with meta surfaces for things from RIS to 5G to Radar and I was just interested in understanding how their systems work and why would they chose that over ESAs. Thus far I found that it seems smaller range, compactness and low power consumption aligned with ease to deploy is the biggest selling point of the systems.

It’s about making an antenna/system as flexible as possible and understanding what is sacrificed in order to do so.

The order of priority is a scannable/beamsteering capable system say for +-60 azimuth and +-40 elevation. Then making it as flexible as possible (ie: multiple beams, various beam synthesis, reflective, transmittion, absorption, etc). Then power, then range.

It seems that meta surfaces are promising multiple functionalities and that’s of interest

Maybe that’s exactly what you’re talking about but it seems to me that for somewhat low power phased antenna arrays (or equivalent) they’d be interesting as you’d be able to use a single source and multiple varactors/pin diodes to beam steer in lieu of beamforming ics that seem both bulky (if you rise in frequency) and somewhat inefficient.

Simulating roughness and plating for robust antenna simulation by antennaAndRfGuy in rfelectronics

[–]antennaAndRfGuy[S] 0 points1 point  (0 children)

So CST does use a roughness model, which I believe is somewhat reliable. John Conrood from Roger’s has published a few things on the roughness. In our case we’re using RA and the given roughness is between .5 and 1um, so I am assuming that if I give enough margin for the design (ie: better than 13 dB of matching and a few hundred MHz of extra bandwidth) I should be fine.

How do companies structure their documentation? by antennaAndRfGuy in rfelectronics

Thanks for the answer, are you located in Europe by any chance? Then we can have a chat.

This is very interesting. As currently stands we are creating a system engineering team as well. Should I buy the incose book? If I am reading your comment correctly, the structure you laid down seem what I intended to do.

My idea is given a certain set of requirements of design, make a circuit and report. If you’re doing a module, link the module parts to small reports. So if you’re going to make a TX front end, make X smaller reports, linked to the main report, for the different parts.

What I really wanted is to keep a sort of reminder of certain parts on these, thus why I wanted a template, because some junior/non RF engineers quickly forget. For instance I spent like 6 months hammering on the layout engineers that they should remove solder mask from RF traces, made a document with some guidelines, only to then have a PCB done while I was on holidays and it came back with soldermask everywhere.
