  1. 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
  2. Ignore second image, wrong drawing
  3. 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.
  4. 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
  5. 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
  6. 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
  7. 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
  8. I'll try to draw and simulate both of them on CST
  9. Or is better to go on this?
  10. For this construction and calculating dimensions for 2.44Ghz biquad, should the 2 sma's be isolated mount on reflector?
  11. Have a look at this: https://www.printables.com/model/886120-lte-4g-biquad-antenna-806mhz/files
  12. 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.
  13. Dual Port Biquad, correct and suggestions please Biquad.cst
  14. I think it is better 3300-3800-OPT.cst
  15. 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
