Hi all!

I'm a newbie in RF simulation, and I've been asked to design an antenna with 10 dBi gain at 870 Mhz for my undegraduate degree thesis, with CST.

However, I've found nothing but this recent paper which proposes a reader antenna with a maximum gain of 8.9 dBi at 915 Mhz.

Here it is:View attachment 05482113.pdf

I have to say that the authors do not specify thicknesses of some materials,
so I had to choose these ones by myself.

When I simulate the antenna, s11 does not drop to -20dB (about...), but remains almost near to 0 dBi :( (Far fields are even worse).

I was wondering what can be wrong with this design of mine.

If you want, I can send you my project to see if there are mistakes.

Best regards
 

It is much simple to design the patch antenna with Ansoft HFSS Antenna Design Kit which you can find on web. Just specify you frequency, substrate then it will build the model automatically for you. You can find in from the web our ask Ansoft service team for that. You do not need to do it by hand.
 
Hi,

I've successfully managed to simulate the design, so I don't need help anymore.

Hey!

I was trying to simulate the same structure. But I've some problems implementing that structure mentioned in the paper. Could you please forward me your Simulation files to my mail id: kkaushik@ymail.com
 
This microstrip antenna can be simulated using **broken link removed**.
