An antenna with dual polarized, dual ports design, unexpected good results!!! RoundPatch.cst

Hi, don't find a way to do this, please tell me and I'll move it

May the double port cause the lower dbi gain or the whole parts placement, also I did not add a component in this, it's a testing project and someone that knows more than me could modify it

Corrected drawing BesterTEST.cst

Based on pre-cuted brass disks by Aliexpress (also there are copper disks): (https://www.aliexpress.com/item/1005008356725365.html?spm=a2g0o.cart.0.0.341d38daIYDifj&mp=1&pdp_npi=5%40dis!EUR!EUR 3.35!EUR 3.08!!EUR 2.92!!!%40211b876717506983783034052ec3c6!12000044708261645!ct!GR!169332860!!1!0 I made the attached antenna based on standard dimensions so that can be easy constructed. I think the results are good enough, but I don't like the farfields output, anybody to check and suggest corrections on it but without changing disk sizes, maybe distances?

Trying to design and test different antennas, I post my .cst files for everyone that wants to redraw or recalculate them, or even to have some ready to 1.cst 3.52-1ghz.cst 3.52-2ghz.cst 3.52ghz.cst 3.52ghz-new.cst 3.52ghz-ShortTubes.cst 4-Planar.cst 4-Planar-BASE.cst 4-ROUNDS.cst 4-ROUNDS-ports.cst 4-SHEETS.cst 3300-3800 MHz BESTER.cst 3300-3800-OPT.cst 3300-3800-OPT-BRASS.cst 5645BiQuad.cst Antenna1.cst Batwing.cst BatwingCrossDUAL.cst Bester3Disks-2.4.cst BesterSquare.cst BesterSquare-3.5.cst BesterSquareShort.cst BesterSquareSMA.cst BesterSquareSMA-3.5.cst BesterSquareSMA-4G.cst BiQuad-CROSS.cst BiQuad-NEO.cst DISH.cst KATH-DRAW.cst KATH-DRAW-BASIC.cst KathreinPLAN.cst Round-Planar.cst SquarePatchYagi-2.4.cst SquarePatchYagi-3.5.cst T-Antenna.cst

Ignore second image, wrong drawing

According to all Bester plans, please what should be the placement of dual polarized antenna, in vertical position or in a rotation of 30°? Thank you.

Seeking for something similar but no luck, so decided to go on by trying different procedures on design according to this one:https://www.rfelement.com/products-72.html

Thank you my friend, I'm new on CST design but trying to learn by seeking online for help, also continue to design different models and simulate them for knowledge. I liked the Kathrein antenna design that is simple and very stable and trying to make a prototype at 3.5GHz center frequency and a bandwidth of 3.3-3.8 because that is the working 5G area in Greece

OLE, I think getting better by working on CST, that's my new design for a similar to Kathrein element, not so good but looks to work, also if mounted on a parabolic dish, maybe it give much more gain. Now trying to decrease the VSWR KathreinPLAN.cst

Also, I'm trying to simulate a Kathrein antenna element for 3.5Ghz, but results on CST look very bad, I like this Kathrein design and if anybody wants to try making some corrections on this it would be a good antenna to use as dish feeder 4-Planar.cst

I'll try to draw and simulate both of them on CST
