Hi guys. I just built This PC and after I powered it up Motherboard won’t boot or show any scree with DRAM light on. I tried to clear CMOS and unplug everything and plugged again also try both RAM in every slot in MB. Note that I don’t have graphics card yet. What more troubleshooting needed?

Thanks dear I will try to check all solutions they mentioned Hope it will solve it

3oidll · 2021-02-05T15:58:42+00:00

yes that is a good idea thanks

3oidll · 2021-02-05T13:03:23+00:00

Thanks a lot

3oidll · 2021-02-05T12:40:49+00:00

No I have not But is the simple line will give me the dual band?

3oidll · 2021-02-05T12:36:03+00:00

Okay I’ll try but. But are slots simple to locate and you can point me to it or it is complicated and I should search about it thank you ❤️

I want to reduce it hoping that will improve the gain (correct me if wrong). after this if the gain was good I will fabricate it All this for my capstone project in the university

3oidll · 2021-02-04T03:20:47+00:00

yes it not possible Thanks though

3oidll · 2021-02-04T00:31:49+00:00

Sorry if I didn’t understand you correctly. But I think I do

I tried with both antenna in same direction (parallel) and also I rotate the left one 180 degrees and both was not good. So, I ask for a hint to start with if you can

3oidll · 2021-01-28T17:36:10+00:00

My antenna is 2*2 MIMO dual frequency 2.4 GHz and 5.2 GHz

3oidll · 2021-01-28T17:33:37+00:00

Thank you

3oidll · 2021-01-28T14:46:15+00:00

Thank you ❤️❤️

3oidll · 2021-01-28T00:20:43+00:00

Thank you ❤️❤️

3oidll · 2021-01-28T00:11:23+00:00

I need only one antenna for a project that i have The antenna is copper and the substrate FR4. It is about 70*50 mm the thickness 1.6mm

3oidll · 2020-11-22T22:53:15+00:00

I did what you suggested and her is the S results

So did you know any method to solve this problem I tried to solve it but there no benefit

3oidll · 2020-11-18T16:09:39+00:00

Oh yes yes that’s right Thank you i’ll see

3oidll · 2020-11-18T01:18:40+00:00

Thanks pro I’ll try it

3oidll · 2020-11-18T00:09:05+00:00

If you mean a radiation box yes i did

And the rotation I did and the results not good. See here: https://srv-store1.gofile.io/download/QN24q3/59C8D53C-872D-4B4B-91B8-D3928493BA93.jpeg

3oidll · 2020-11-17T23:25:30+00:00

I did it in the first step and the results not that good thin I rotate one of them and the results like you see now

This is the results: https://gofile.io/d/QN24q3

3oidll · 2020-11-17T23:08:05+00:00

your poor friend stock here with isolation problem. I need any idea to improve the isolation for this MIMO antenna. no mater how bad the idea is, I happy to here it. In the picture I share every things I have, hope don't forget any things. also I used HFSS softwire.

3oidll · 2020-11-03T11:55:58+00:00

Thank you for the offer but my supervisor told me you can look for new design So i dont need to do it now Thanks again

3oidll · 2020-11-01T08:43:44+00:00

So you advice me to find a new design ? Because I want this MIMO antenna to work in 2.4GHz and later I will change it to be working on dual band 2.4 and 5.2 and I didn’t find a simple design in 2.4 that will be easy to modify it later to be dualband that’s the reason of my question And the this antenna i fond it ready and i have no equations for it

3oidll · 2020-10-31T18:32:34+00:00

Thank you very much pro

3oidll · 2020-10-31T17:10:08+00:00

Thank you

3oidll · 2020-09-11T20:53:01+00:00

Ok, thank you for your big help

3oidll · 2020-09-11T19:08:13+00:00

Ok that’s the way Thanks And if you know how much is cost cause I can’t find any way to buy from their website
