"""both antennas work...!!!!
-
I'm sorry but I deleted the file...!!!
-
maybe so ...
-
","it can also be without a connector, with a straight coax cable...!!!
-
,,,a constructive alternative, without polystyrene foam, on the air....!!!! ,,, it cuts off the patches, metal spacers equal to the height between them...!!!
-
,,,is that something you are not interested in....??? without polystyrene foam 300x300mm -PCBreflector 15dBi-gain
-
,,,that which you want...!!!
-
,,, с переводом на английский, пожалуйста ... !!! ,,, with translation in English, please ... !!!

где вы видите короткозамкнутая ... ??
-
это проще, но вы можете поставить 2 болта it's easier but you can put 2 bolts
-
,,,okay,try it...!!!
-
,,, read this topic carefully....
-
,,,success...!!!
-
And all these lies are ...

4,5mm

increases(little bit)antenna gain in directivity ,,,

,,,how to see current distribution from cst...?? When looking at the surface current monitor you first of all should choose one of the given results for example the "Abs".There you can choose a view thats called contour. It shows you a result like in your attechment. If you want to see the distribution in a special plane, you have to do a right-click and then choose 3D Fields on 2D Plane. Then choose the Plane you want to see.

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

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...

A new patch format...for broadband

...with coax phasing lines...!!!!
-
An antenna array in which two or more dipoles are stacked one above the other to obtain greater directivity...
-
This antenna does not have the correct dimensions for the subscribed frequency...
