antena smc pacman circular mimo my idea

39 posts in this topic

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

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...

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?

"well, but see that the antenna output impedance is not good...!!!
"cst, I'm using

what is the result of impedance that is not good?

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

,,,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

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

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...
