ADS Antenna Simulation issue

[smithsdr]

Dear Members,

I am new to this forum. I am trying to simulate a micro-strip patch antenna in ADS momentum. The tutorial I am following is

**broken link removed**

But results of my simulations are not right I think. I have also attached my results

Any pointers on what could be the issue ? Any tutorial on designing a micro strip patch antenna in ADS momentum would be appreciated.

it is a nice elaborated tutorial . you surely would be missing something.... are you sure you followed each step correctly??
better ask "specifically" if something in that tutorial you don't understand!!!

Yes its a very nice tutorial that's why I chose to start with it. I double check all the setups and couldn't find as to what I am missing or doing wrong. Currently I am unable to understand the results. My antenna looks like https://obrazki.elektroda.pl/7793856600_1381510162.png. I have also attached the antenna layout.

Is it exactly the same frequency and dimensions as in the tutorial that u r trying to simulate or u have reevaluated the dimensions for other frequency ?? Also try to put up some pics of the meshing and the substrate specifications the you have defined !!

I have used the same frequency and dimensions as in the tutorial. Snapshots of meshing and substrate are

Well U have the setup exactly as in ur reference but i do not see the meshing on ur antenna structure. The kind of plot that u got has to be due to un proper meshing. Try to increase the mesh frequency to double., There has to be smaller boxes appearing on ur structure..!! Increase the mesh frequency and put a snap of ur structure after meshed..!!
