0.25 is disc thickness, 10 is SMA connector's distance from the radiator's edge, both in millimeters.

The diameters of the reflector, radiator and first director are 90, 68 and 54 mm, respectively, with 5.75mm and 9mm gaps in between.

Could you guys tell me if you think this design could work? I am building a 2.4ghz yagi disk cantenna, but I am unsure of the separation distances and copper circles.

Am I correctly connecting the SMA to the antenna? For some reason it isn’t performing as good as I wanted it to.

feedpoint (SMA) to the center c=20. is there any standard method on the calculation? most of the time it is about 1/3 to 1/4 from the R=90 in this case

,,,the  feedpoint is chosen relative to the vibrator and not to the reflector...!!!

,,,as you can see, this is chosen to ensure a wide frequency band...!!!

oh ok, so the feedpoint location is it safe to say around ~ 1/3 length location from the center of the V? I still cannot find the correct formula for this. or is it  to be autocalculated in the CST software?
