MIMO dual band antenna for alfa awus036ach

[Lonely Angel 0]

Hello everyone. I need help in creating the antenna for alfa awus036ach. Need directed antenna for range N and AC. Who will be able to count dual band antenna and put drawings?

Hi buddy,

you want to replace the two dual band antennas...????

[Lonely Angel 0]

Yes. Because antenna connected via technologies MIMO. I think to change one will not make sense.

[Admin 2561]

can you do that ..?

 

[Lonely Angel 0]

I think yes. But on the forum lan23 you've posted calculations dual band antenna, Harchenko with increased 10-18, Dbi. I think it more interesting.

[Admin 2561]

show me where...??

[Admin 2561]

"do not you like that?

[Lonely Angel 0]

I like it, but this looks more functional

", ooo yes, that's a long time ago ... !!!
I will resume this issue ... !!!

,,,this it"s....?!

This is something about what I said. I think it better. If wrong, it is correct me. You have left the drawing from her? Immediately asking for this antenna have to do such a reflector in the form of a cup or you can make two antenna for MIMO and placed them in a rectangular box?

[Admin 2561]

"I do not know, let's see, the antenna is old and needs to be improved...!!!

[Lonely Angel 0]

Great. If you happen to improve, I'm very glad

[Admin 2561]

A slightly modified version ...

 

[Admin 2561]

But I think it would be better....

 

[Lonely Angel 0]

Great! You can get the drawing with the size?

[Admin 2561]

"""okay, after finalizing some optimizations, I'll post the dimensions...!!!

[Lonely Angel 0]

Hello. It turned out to optimize antenna?

,,,not yet, but the end is near...!!!!

[Admin 2561]

I think it should look like this, but it need to make a 250 Ohm adaptation...

[Lonely Angel 0]

Ok. Thank you. It's pretty antenna. Could you still to send the size of this antenna?

[Admin 2561]

These are the dimensions, impedance adaptation remains to be done...

[Lonely Angel 0]

Thank you! It's great antenna.

[Admin 2561]

,,, that's how it should look like the adjustment line, on FR4 #1,5mm...

Afraid to sound rude, but I think complex in the manufacture of the antenna. Can be will be easier to do patch antenna with increased 15 dbi? If You will not difficult.

[Admin 2561]

15 dBi with only 4 patches...!!!
