Dear support team,

 

Recently I try to simulate a very simple patch antenna working at 2.45 GHz, but it show an error message as below, please check it:

 

ERROR 3849: Wrong specification of the medium for a metallic triangle 

 

and I try to open POSTFEKO and use 'Find Element' method, to see the problems occurs by which triangle, but two meshes seemed like not overlap.

 

<?xml version="1.0" encoding="UTF-8"?>Capture.thumb.PNG.4c1bdcf53fe2d458db5937d425b3f7da.PNG

 

can you help us check what's going on in my simulation?

 

Thanks a lot!

 

BR/Marcus

    Hi Marcus

     

    I see there are many parts in the geometry tree. For a continuous mesh to be generated, you must Union all the parts.
    Then you must set the appropriate Region and Face properties.

     

    I would also rather use a waveguide port.

    Dear Mel,

     

    I have tried to union all the parts, and it still didn't work.

    And also, due to there is an error if I use waveguide port, so I use lump port alike, to excite it.

    It would be grateful if you can help us modify the settings for this simulation.

    Dear Mel,

     

    Is there any update for the modified .cfx file?

    Looking forward receiving your response.

    It would be simpler to first get the design working with a simpler port construction, such as the edge feed.

    Attach the cfx.
