The error bars indicate to what extent each matrix element deviates from the optimal tuning. The CST Filter Designer 3D environment is shown in the screenshot below, with the measured S-parameters read from the R&S®ZNB. In this particular case, port 1 and port 4 are de-coupled, so one can expect S14 and S41 to be very small. Given an accurate manufacturing process, the same result will be obtained from real measurements with the R&S®ZNB when the hardware is tuned to match the simulated coupling matrix. Although CST MICROWAVE STUDIO® can provide a wide variety of results, this tutorial concentrates solely on the S-parameters and electric fields. The filter model was designed with CST Filter Designer 3D and simulated with CST Studio Suite®. This provides the necessary information to optimize the filter hardware through its tuning mechanisms such as screws, variable capacitors and varactor diodes.
The R&S®ZNB is the leading vector network analyzer for production environments with a focus on speed, dynamic range and ease of operation. I want to decrease the mesh size in CST microwave studio. The whole numerical simulations are completed. Actually I have found some answers that might help in calculating the near field using CST studio suite specially on.
For real-world tuning, CST Studio Suite® supports USB, socket and Ethernet connections for a wide range of Rohde & Schwarz vector network analyzers. Each unit cell can be independently tuned, and different coding sequences for the full model would result in the different backward scattered fields.
