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

Or is better to go on this?

For this construction and calculating dimensions for 2.44Ghz biquad, should the 2 sma's be isolated mount on reflector?

Have a look at this: https://www.printables.com/model/886120-lte-4g-biquad-antenna-806mhz/files

Two ports for a TP-Link MR-100 router outdoor antenna, it has 2 sma antennas, and I want to replace them for better signal gain, as the router cannot fitted outside, because need protection from rain. I made a biquad in antenna-magus, exported to CST, and then doubled the elements making also a larger reflector.

Dual Port Biquad, correct and suggestions please Biquad.cst

I think it is better 3300-3800-OPT.cst

Modified the antenna but I'm getting errors, by your free time have a look and correct it please 3300-3800-1 MHz BESTER.cst
