,,, okay, so the program works and you know how to work with it...!!!???

unfortunately I don’t know, I have no experience. But I will look to understand

you got few sets of sizes for BatwingS in this thread

you can just make it, you do not need program for this

these parameters / calculations and dimensions are not available

this 2 crossed even better...because almost no overlay

[Admin 2421]

For now,,,this it"s the best...!!!

,,, let's see further ...!!!

if used as an offset antenna feed - the size is too big

[Sl4va 11]

Theoretically, can it be done on a double-sided PCB, by etching?

I made these a month ago. 

Made for these sizes:

Material - copper sheet, 0.6 mm thick

But what if you put it in a reduced size "bucket"

by type as below picture

I have another idea....

put them crosswise and you get a decent distance between the points of contact. Maybe this is better?

this is some shit

just maki this MIMO "nazi cross" with small flat reflector (without sides):

Initially, I started a conversation Batwing, how to compose for a satellite dish in Mimo

one more time - to make irradiator for satellite dish just just make this MIMO "nazi cross" with small flat reflector (without sides)

MIMO "nazi cross" with small flat reflector = satellite dish irridator

You won't isolate by tweaking ONLY the feed point...the WHOLE electromagnetic diagram must be consider (All irradiating elements and surfaces)(for ISOLATION that is)

SIMPLY put...: TWO COMPLETELY SEPARATE ANTENNAS are better (for ISOLATION of Ports) than two in the same cavity or close to each other...ALWAYS

But what about Kroks and Antex? They are mimo

I wanted to show that it was so. Bend the middle so that the butwing petals lie in the same plane and do not touch

not sure you can feel the difference if you put one batwing 2-3 mm above another or use this fancy band in the middle

are you going to use it for 4G? if so, there will be no difference

Yes, for 4g!

And about the intersection: I found a pair of intersecting feeds on the internet, just like the Batwing in the admin's photo. And one resembles the shape of a batwing.

Calculate its size. Who can help with this?
