    Error using CST: Mesh is empty

    Hello! I would like to ask you about this error:Mesh is empty using CST. Any suggestions about which could cause such error ?! Note: I am simulating a structure which has mm as a unit and GHz FOR THE FREQUENCY unit. Thank you !!

    electrical and magnetic coupling

    Greeting! I want to know how to distinguish between the cases when there is an electrical coupling an those we have a magnetic coupling. an example is shown in the picture attached where both occur but I couldn't say/explain where or why the couplings occur. Hope I made myself clear...

    swaped E and H plane under CST

    thank you very much! I feel like confused about the figures of volker they don't tell much to me :-( Ps: could you please specify the planes by xy and yz the terms horizontal and vertical depends on the structure positioning. thx!

    swaped E and H plane under CST

    well I am confused now more than I was, but one comment seems to solve the problem by volker@muehlhaus. what do you think?!

    swaped E and H plane under CST

    well it is a very ordinary loop planar antenna with a partial ground plane. I have attached the results that I get. thx!

    swaped E and H plane under CST

    Hallo, I have a loop monopole antenna while visualizing the E and H patterns I get them swaped (E must be H and vice versa). Any ideas about what could cause such thing! Note: I took E plane (phi=0º) and H plane (phi=90º) Regards!

    Method of analyze SIW antenna

    Thank you, very much for the open sources, I appreciate it! could you give any arguments for your choice or references , I will be grateful! because I have been looking into the literature for a quite long period and I can't decide maybe because I am new to this field ! regards!

    Method of analyze SIW antenna

    I didn't build an antenna yet but it will be a slotted one (simple and not stratified). Now, I am confused about the adequate method that could be applied to get the characteristics (phase constant, attenuation,..etc), as going through the literature most used ones are MoM and Mode Matching...

    Method of analyze SIW antenna

    dear all, I want to know which method is more adequate to analyse the characteristics of a SIW antenna and what are its advantages compared with the rest of the methods? many thanks!
