    [SOLVED] Positive S11 Parameter - Sample HFSS file uploaded

    hello all, thanks for ur reply, PlanarMetamaterials please,how can i define the integration line manually? flanello i tried several times to change the frequency range and make it larger but it gives me error on the simulation((the calculation seems to be unstable!))

    [SOLVED] Positive S11 Parameter - Sample HFSS file uploaded

    - - - Updated - - - the port size is 6 times as wide as the width of the microstrip line(1.9) and 5 times as high as height of the substrate(0.813),but when i use this height i got positive S11 in both side,and when i change it i get different result like the one i sent it to u before .

    [SOLVED] Positive S11 Parameter - Sample HFSS file uploaded

    hi PlanarMetamaterials , thanks for ur help, actually i changed the dimensions of the port and i reduced it's height, but S11 became like in the pic below!! i think it's much better but still there are frequencies have a positive value, wt's ur suggestions?? regards

    CST microwave studio simulation error

    Hi, i constructed a multilayer rectangular DRA, but unfortunately after the simulations i got 3 errors: 1.(The first mode at inhomogeneous port 1 is hybird.this could lead to an inaccurate energy balance.please check ur structure) 2.(24 mesh cells are represented in staircase mode and have been...

    Setting of Microstrip feeder

    Hello guys. I need some help regarding the setting of microstrip line precisely about the impedance calculation. For microstrip line the impedance changes with strip width, substrate and height of the substrate.the width of the microstrip is calculated using a tool known as impedance...
