MiMo Patch Antenna on PCB

[Admin 2421]

,,, a few years ago I launched on the web such an MiMo  patch antenna on PCB which through practice proved not to rise to its simulation level...

 

And that's only because the isolation between ports was not taken into account

[Admin 2421]

,,, and for that, I decided to modify it MiMo the antenna on PCB, below I present a simulation with this antenna which has a good isolated ports,

[Admin 2421]

And these are the files for PCB printing

 

MYPCB.dxf

MYPCB.frw

 

With some technical details,,,

Hi!
What will be the distance from reflector to patch, when patch manufactured with a laser cut from metal of 0.7 or 1 mm?
like this, and will the geometry change? I want to make antenna.

Best regards!

For which frequency do you want this antenna to be...????

[Tesseract 1]

Channel 11- 2,462 GHz.

Tesseract, tell me ,you have the KOMPASS program...???

[Tesseract 1]

Yes, if You mean ASCON KOMPAS-3D.

[Admin 2421]

Okay, then I can send  to you igs*file,or dfx*file for laser cut...??

[Tesseract 1]

OK, great!

Dear Admin. I absolutely love your antenna's design, i made one, the big one ( error when opening by CorelDraw) and the same to your size. but i still have some question about your design. please enlighten me if you have time.

1. the space between the PCB and reflector, is it necessary have to 2.5mm, like your design, or any number, 5, 7, even 10mm, i had read 10 page in your threat attachment to figure down, but no answer.

2. if we increase the space between PCB and reflector, it make better or worse.

3. like some of your antenna design, i see something like a screw in the center of antenna path, which connect to reflection. but in this PCB antenna, i don't see it. please watch my attachment

4. the PCB antenna,we have to use 1 side PCB or double side PCB. i did 1 side,  because, i watch some video about antenna was made by china. some of it have to double side, some of just one side.

Sr for some stupid question. i just amature, trying to DIY. that my passion.

Good Night Admin!!!

,,,hi buddy...!!!

,,, first of all I tell you that it is not absolutely necessary to present my images in copy
,,, the distance between the reflector and the PCB is chosen to stabilize the impedance of the antenna
,,, the connection of the vibrator to the reflector by screw, influences the impedance of the antenna but it is also possible to remove the electricity
,,, it can also be double-plated PCB, but it must be of good quality

Admin.

Thanks you. I will make by one side, Bc the PCB in my country not good enough. 

I' try to make distance between PCB and Reflector close as your design.

I watch your discussion , and saw the H=7, can i apply to PCB board, In this threat ???

[Admin 2421]

,,, no, 7mm is too much ,,, maybe 4.5mm compared to the copper layer ...!!!
,,, but tell me what PCB you want to use and I will try to help you...!!!

Good morning Admin!!!

The PCB is FR4 1.6MM. the best quality in my country with 18um/side

actually may i add more path on your antenna design. with 4 circle or 4 square. like the yellow antenna i attached. it have more 4 circle on top. it will increase frequency range???

[Admin 2421]

Good morning Eric...!!!

,,, you are interested in the yellow model...???

Yes, Sir.

I'm interesting with the circle, can i ad 4 circle to the middle of path. like this picture

can you give me a PDF file of yellow model. and the number of square and circle patch

[Admin 2421]

Okay Eric, but you want your vibrator in the air or on the PCB...???
