The description contains a power section. it is missing from the simulation.

This is all well and good, but what does this have to do with me? Did I say that's not true? The option that was originally posted by the Admin in the topic is not a circularly polarized antenna. Without phase-shifting elements in this design it is impossible to obtain circular polarization. This is clear to me. in the initial version it is a regular mimo dipole. Perhaps the admin used a phase shift on the port when modeling. I have nothing to do with this.

???

you can try to do the trick with mimo. copy all the elements and rotate the copy by 90 degrees. it seems to me that the polarization decoupling should be good.

that's what I was talking about It's quite possible to stretch it to 1700-2700. I think a parasitic element should be made above the lower patch for better matching. or this tipe patch

or 1700-2600 )

hi! try to move to LTE. low band to 800-900 and let's see where the high one will be...

A good start! It remains to choose the sizes to expand the band 1700-2700. Once you do, I’ll give you another good idea.

without plastic protection

8x16...Small gain... should be 30dbi ~30 dbi

14 dbi - very well?

Use ordinary metal shears for cutting. use a drawing compass for marking. what was recommended to you by the message above applies to cutting ceramic tiles or plastic. when cutting metal with such a tool of metal sheets, very serious injuries can occur. do not use such cutters!
