,,,,something like that...
 

I never made a thing like this but I never photographed because my smartphone was stolen

but now I focus on making my own antennas, but there's a word "plagiarized"

its my idea

Acri brother, please excuse me that I did not pay too much attention to this type of MiMo antenna, but now I think this is the best option...

this is my first pacman mimo antenna ....
posting on the forum is my idea so i can save the material but generate mimo antenna

where reflektor?

please mention the ideal value for s11, s12, s21, s22 .....
please mention the ideal value for s11, s12, s21, s22 .....
because when i try mimo sectoral simulation i also get some times value as above

brother, please send file cst for sxt

I am interested in this model, please share the actual size that has been tried and working

 

diameter 62 mm

ok brother,

actually I want to learn the process of making the cst file, for adding knowledge

I think this is a pretty common thing to do. Lots of point to point wifi links use dual polarisation antennas. In fact it can actually be the same antenna so long as it has good isolation between the ports.This antenna does not have this... S12, S21 must be> 30

 

 

Be careful, port to port isolation is not the same as polarization isolation. Polarization isolation is a useful technique when you want to transit two simultaneous signals and both can exist. It is like transmitting on vertical and horizontally polarized antennas.

If you are transmitting through a Wilkinson to two antennas (one RHCP and the other LHCP) you could be in for some interesting effects. The resulting polarization will depend on the rotational orientation of each antenna and any additional phase difference in the feed lines. You will end up with some elliptical polarization with the axial ratio and major axis probably in an unexpected direction. Sorting out what you have will be fun.

 

THE BEST IS THAT...

brother please send this file cst

I will try it, if it does not work I need your help to make the tutorials to make it easier for me to understand

,,,success...!!!

brother, I want to make an antenna with
reflector pxl = 68mm x 67mm
driven = 52mm x 51mm
director = 47.6mm x 47.2mm

distance reflector to driven = 1.7mm
distance driven to director = 3.5mm

please help me to make a tutorial in CST Studio

I was very confused when I made it in CST studio

alhamdulillah
i fix trouble
i am edit license.dat date to 1 jan 2019

hahahahaha

brother applications other than cst?
because my vga is not support

ok nice info brother

what distance is suitable for antenna above
because the distance is exactly the same as the antenna made by SMC networks

reflector-PCB distance

what if the reflector is 11cmx11cm?

thanks brother i will be try

actually there is still another smc pacman mimo version of antenna i am still there ... maybe next time i will share and once again please simulate

if I can ask what program do you use?

hallo admin,

I need a simulation, from my idea for this model antenna that I've developed ... the original version of this antenna is siso...
during the trial period for the last 6 months I use for my wireless client no problem at all

please make the simulation

thanks admin
 

what is polarization?
vertical or horisontal?

while casually making 5.8ghz mimo nsm5 design using corel draw, size already precision, who knows something can improve again

 

nanostation m5 paulanet.cdr

not nsm5 but NS5

,,,yes, the VSWR it"s bad...!!!!

,,, but isolation between ports and impedances is good !!! !!!

do you think it is worth using or not?

in my opinion, all mikrotik radio products, the shape/design looks less professional, very different from ubiquity. 

hahaha, my opinion quality better mikrotik

I also usually like that, but mimo sxt2 antenna looks more simple and efficient

Anyway, my antenna is better...!!!!

yes brother, i used your antena for siso
but i am looking for mimo model

I do not know
that's all the information I get from friends
