One antenna to rule them all...
Daniel Uhrenholt, Fri Nov 20 2009, 09:55PMHi all.
It has been a long time since I've been on the forum, because of stress at work and other things...
Finn Hammer encouraged me to post some pictures of the latest project at work, so here you go:-)
In the last two and a half month I have been working on a antenna array with some of the
electronic engineers at work. It is 16 Quard-Ridged Horn antennas with a frequency range of 700 MHz - 6 GHz, placed in a sphere shaped form. They are used by the University to do some measurements for the next generation of mobile communication, as they are working on this at the moment:-)
Traffic crash to the left, antenna to the right:-)
I designed the set-up and antennas in Solid Works, and made all of the antennas on our CNC machine.:-) We did not do the maths for the antennas, Denmark's biggest computer did this for us:-)
Okay, I promised my boss that if I use the pictures I took on the internet, I'd had to link to the section that is doing this research...
Cheers, Daniel

Wonderful stuff, Daniel!
UWB antenna design is one of the most creative areas of RF engineering at the moment, and you are lucky to have a part in it,
Stella.

No matter how you slice it, that is one hell of piece of artwork if nothing else. If one were like myself (inclined) to think about how much work goes into anything that complex; would be astonished! Whether that thing catches complex radio waves or looks really good on your coffee table its an accomplishment. I can admit that i don't know that much about rf antennas but i have years of machining experience and that my friend, is impressive.
Fantastic work. Don't ever stop doing jobs like that and i will never be mad at you

Interesting,
the cluster probably partitioned more than a few nodes to model this design.
What is the gain in 1.2 to 2.3 GHz?
How stable is it with temperature changes?
Bird prevention measures would seem to be ready too....

Thanks for the comments, it was a pain in the A** to make:-) But this stuff is what I do on daily basis, and it is exiting and fun.
Carbon Rod,
I don't have the calibration report or the simulation papers here at home, so I can't give you any reply on this before Monday morning...
Cheers, Daniel

I...I think I just had a nerdgasm.
Daniel, how much do I have to pay to get you to smuggle one out of the lab for me?

that is AWESOME.
Those don't even look like antennas, I would think it was a sculpture if not for the LED's.
I love the texturing you did.

My mum wouldn't be impressed because it won't pick up BBC Radio 4. (That's 198 KHz for those who are unfamiliar with UK radio stations)

That antenna looks awesome, Daniel!
I once made a Tesla coil whose resonant frequency turned out at 198kHz. It made an excellent antenna for Radio 4.

Finally someone solved my wifi problems, where can I order it Functional and a piece of art for sure.

Nerdgasm LOL
Are you talking about one horn, or the whole set-up:-) I would estimate the price of the flower to be around 160000$... But this is research equipment, so we really don't care about the price, because we don't earn any money on this stuff:-)
I'm currently working on my website, and this time it will be in English. There will be a lot of the neat projects I worked on explained there, and of course some of my Tesla Coils:-)
Cheers, Daniel

Wonderful piece of work Daniel! I love science that is unintentionally artistic at the same time.
I see they have included polarization along with spatial diversity. I imagine this thing is going to be feed with the mother of all Butler matrices?
Love exponential tapered ridged horns, simple and wide banded.
Great work
Scott

It's not often that art and engineering come together so well. It's a beautiful metal flower of RF goodness.
I'll stick with with my trusty BiLog

Does that make Daniel's antenna a bilogosphere?
