[Help] @nsoft Designer Probe feed antenna
I need some help using @nsoft designer to generating a probe feed patch antenna operating @ 10GHz. I tried generating a patch using the dimensions given by the estimate feature but got strange results. (Could it be the size of my probe?) Maybe someone can please point out my mistakes.
You help is very much appreciated.
Thanks in advance.

Hi all,
it seems that no one is free to help :( I've done a 2.4 Ghz p@tch and its works ok in designer. Attached model. But 10Ghz still resonating @ 6GHz no matter what the probe size. Can anyone shed some light please?

Hi,
I am devloping a 2.4 panel antenna based on 4 dipoles.
I found a doc on the internet with all the calculations for working out the exact size for a p@tch for a given frequency.

I have created a spreadsheet but its at home right now, I'll upload it later.
Input is frequency, dielectric constant etc.
May be of use to you
Can you give me the details of your 2.4ghz p@tch.
Can @nsoft designer be used to produce return loss, bandwidth and gain pattern?
I'm using Zelands IE3d at the moment and it is a bit complex.

Hi covenlink,
thks for the very useful link. :D
@nsoft designer has an estimate function (based on cavity model) for standard probe feed patch antenna. I remember reading somewhere that the cavity model has certain limitation; maybe that might be the problem with using the estimate feature with the 10GHz patch. Please tell me if I am wrong because I am really not too sure. Given the substrate material, freq and desired vswr, the estimate function in @nosoft designer gives an approximate dimension and probe position of the antenna. I will upload a pic file of the antenna later when I have the opportunity. 8)
Meanwhile , I will have a look at the thesis.
Cheers for your interest.

You may like to try using inductive loading...
