    why return loss results of HFSS 3D module and layout is different?

    Thank you for your efforts. It is highly appreciated. Yes the orientation is not exactly aligned along xy axis they it is design intentionally like that

    why return loss results of HFSS 3D module and layout is different?

    sorry for inconvenience 1629317408 actually dxf was not supported for upload that why i have uploaded rar

    why return loss results of HFSS 3D module and layout is different?

    In 3D layout model there is option to use HFSS solved and Planer EM solver for the same design and configurations. the dxf of top layer is attached the RO4350 substrate with dimensions 98x15.6x0.508 mm with complete ground

    why return loss results of HFSS 3D module and layout is different?

    @volker@muehlhaus you are right that both have solvers, for that i try to compare the result for HFSS setup and planer setup. This time design are completely same but results are still different. @PlanarMetamaterials I also do prefer HFSS 3D module but for co-simulation like antenna...

    why return loss results of HFSS 3D module and layout is different?

    Hi everyone I have design a 2x14 array by using HFSS 3D module and then exported the designed as dxf format and imported it in HFSS layout. When I compare both results they are very much different. The graphs are attached. In HFSS 3D module I have used terminal port for excitation while in...

    Illegal usage of S-Matrix, No impedance found error in cst

    Dear all I am designing a split ring resonator which is exited by waveguide port but when i simulate the design I get two error message "Illegal usage of S-Matrix, No impedance found error in cst and the other one is "Time Domain Solver (HEX) terminated abnormally" does anyone have any idea...

    Reflection coefficient for non reciprocal RF elements

    The Reflection coefficient is S11 when Reflection coefficient Γs is taken as 0 if it will not be zero then reflection coefficient will be different and i am looking for the derivation of this formula Γin=S11+(S12S21Γs)/(1-S22Γs)

    Greber file generation in CST

    Dear all I had design a co-planer SRR array in CST, I am facing some problem while generating greber file. I generated greber file by following method: Import/export-----> 2D files ------->Greber(Single layer) after that cst mark the boundary of substrate and upon clicking ok cst...
