How to plot CCL,TARC,MEG1 AND MEG 2 curves for a MIMO antenna having two ports in CST(Computer Simulation Technology)? Can anyone help me with the steps of these curves?
Greetings, for realization of the stated MIMO parameters, there do exist formulas (https://iopscience.iop.org/article/10.1088/1742-6596/2466/1/012010/pdf). Based on the same, scattering parameters exported from CST could be used to evaluate the needed mimo parameters.
To plot CCL (Coupling Correlation Level), TARC (Total Active Reflection Coefficient), MEG1 (Maximum Excess Gain 1), and MEG2 (Maximum Excess Gain 2) curves for a MIMO antenna with two ports in CST (Computer Simulation Technology), you can follow these general steps:
1. Model your MIMO antenna in CST: Create a 3D model of your MIMO antenna with two ports in the CST software. Ensure that the antenna geometry, feed structures, and port configurations are accurately represented.
2. Set up the simulation parameters: Define the simulation parameters such as frequency range, number of frequency points, and other necessary settings for your analysis.
3. Perform the simulation: Run the simulation to compute the S-parameters of your MIMO antenna. This will provide information about the antenna's coupling, reflection, and gain characteristics.
4. Extract S-parameters: Extract the S-parameters for both ports of the MIMO antenna using CST's post-processing tools. This will provide the necessary data for further analysis.
5. Calculate CCL: Use the extracted S-parameters to calculate the Coupling Correlation Level (CCL) between the antenna ports. CCL measures the correlation between the signals radiated from each port and indicates the antenna's coupling efficiency.
6. Plot CCL curve: Plot the CCL curve as a function of frequency. You can use CST's graphing or plotting tools to create the desired graph. The x-axis represents the frequency, and the y-axis represents the CCL values.
7. Calculate TARC: Calculate the Total Active Reflection Coefficient (TARC) using the S-parameters. TARC quantifies the reflection or return loss characteristics of the MIMO antenna system.
8. Plot TARC curve: Plot the TARC curve as a function of frequency. Again, you can use CST's graphing or plotting tools to create the graph. The x-axis represents the frequency, and the y-axis represents the TARC values.
9. Calculate MEG1 and MEG2: Calculate the Maximum Excess Gain 1 (MEG1) and Maximum Excess Gain 2 (MEG2) using the S-parameters. MEG1 and MEG2 provide information about the gain imbalances between the antenna ports.
10. Plot MEG1 and MEG2 curves: Plot the MEG1 and MEG2 curves as a function of frequency. Use CST's graphing or plotting tools to create the respective graphs. The x-axis represents the frequency, and the y-axis represents the MEG1 and MEG2 values.
Remember, the specific steps and procedures may vary depending on the version of CST you are using and the details of your MIMO antenna design. It's recommended to refer to the CST software documentation or consult with experts familiar with CST for more specific guidance and support.
