On the rest part of pcb will be elements and also GND. So can I set whole surface of pcb as a metal (copper)? Are the simulations done OK? What did I wrong? I attach my design (...)
This may help someone having similar problem. I had gerber files generated in cst MWS (RF designs) but wanted to make a panel for fabrication using Altium Designer. Altium easily generates GBR from pcb document but panelizing all GBR's into one GBR is a little different from what is available in their website (
Hello guys, I am beginner, about simulate on cst MWS and EM topics. Well, let me explain. I have four models of microstrip antennas GSM dual band. I simulated each one with the same conditions, pcb size and thickness for copper and FR4 respectively, discret port (S-parameters) , Open space, and under ideal conditions. After that, I choice the b
In cst how to excite microstrip line in the middle of simulated volume? In cst Microwave Studio how to excite microstrip line in the middle of simulated volume? I use discrete port touching edge of microstrip line and ground plane on the other side of the pcb. Is this correct way to do it? How can I use Waveguide port instead?

The only way I am trying is by making a cylinder and subtracting it from Ground plane. Assuming you have FR4 pcb to be simulated as well, it will have to be 3 cylinders to be subtracted each layer.(top substrate and bottom layer)
I doubt if EM simulation could be performed on schematics until the interconnects are modeled as Transmission lines. And for that you will have to export the topology to pcb, or at least draw the topology in your pre-layout program.
I am not sure whether Genesys can export pcb into other form, like ASCII, ODB++, etc? cst MS do support variety of importing formats.
Hello all, I have been working with cst MWS for about a week now and I am simulating pcb structures, specifically microstrips, both single-ended and differential. I have a lot of experience with 3D modeling and EM solvers. Basically, I was hoping we could share our experiences on what are the ideal settings for the transient solver for ONLY thes
now i'm designing a dipole antenna with apply the discrete port in between the gap.But the problem is I don't know how to implement it to the hardware part, so is it anybody know when i fabricated it on the pcb,what kind of connector i should use to do the measurement on return loss and radiation pattern. Very need you all help,thanks you.
Is it possible to import pcb then set the inputs and other parameters and visualize the electromagnetic field surrounding the board? Theoretically yes. You will need electrical models for all your components.
Hi, I am new to cst as well as pcb milling. I tried exporting a antenna simulation from cst as a gerber file. ISOPRO does not register the aperture list for some reason. All it shows is D999 with 0 width. I also tried to view the gerber file using McCAD. Again McCAD shows an empty aperture table. Any ideas why this is happening. (...)
Hi all, please is there anybody that knows where to find a detailed description of how design studio works? Using the embedded examples, in respect to other pcb capture/simulation software it appears to be very poor in component library and very cumbersome in placing\editing wires, not to speak for mixed dc/ac simulation as needed, for example, t
