,,,you work with CST...???

I'm currently learning to draw and simulate disc antenna using CST software. Still new and learning. I still cannot find the formula to get the feed point / inset feed location. Some said it is about ~1/3 from the V or the radiator

,,,these are the real dimensions...

How much does the material of the antenna matter in this design? For example the difference between copper and steel or aluminum.

h0 = 2mm

,,, the material for the antenna does not matter, but it must be able to be welded...!!!

i made one and it works really well ! What happens if the antenna is out in the rain? Will the water cause a short circuit and potentially damage my adapter (which I keep indoors) ? Or will it just not work properly ?

[Admin 2421]

,,,papus... if the antenna is out in the rain, you have to protect the antenna with a plastic case...

 

,,,or so...

Which 2400 antenna with 75 ohm cable is suitable for a modem?

[Admin 2421]

75 ohm cable (for TV only), not for wireless(modem,antennas,etc) use...!!!

Кабель 75 Ом (только для телевизора), не для беспроводного использования (модемов, антенн и т. д.).!!!

Which one then? 50 ohm?

[Admin 2421]

Of course !!!
