This POSTFEKOアプリケーションマクロ can be used to plot all the standard parameters that are available after a characteristic mode analysis simulation
was performed.
This アプリケーションマクロ is used for calculating mean effective gain (MEG) and envelope correlation coefficient (ECC) for a MIMO antenna configuration.
The MEG ratio can also be plotted.
The Multiport post-processingアプリケーションマクロ allows you to calculate results for changes in the port loading without rerunning the ソルバー. Results that are supported are far fields, near fields, currents and specific port parameters, for example,
the voltage, current and S-parameters of each port.
An interference matrix is a way to illustrate the cross-coupling between ports of a multiport system. Example applications
are antenna arrays, feed networks or power dividers.
The characteristic mode synthesis and design アプリケーションマクロ is a post-processing アプリケーションマクロ that can be used to calculate a weighted sum for the currents, near fields, and far fields requests for specific
characteristic modes of interest. The アプリケーションマクロ uses a modified version of the modal weighting coefficient (MWC) to use the radiating phase when synthesising
the results with the macro.
An antenna array is used to show the workflow of the アプリケーションマクロ and calculate the interference matrix for the multiport
scenario.
In three_dipole_example.cfx, three dipole antennas are created and
positioned a distance from each other. Electric symmetry is used to reduce runtime but
is not required.
Tip: Find the examples in the <FEKO_SHARED_HOME>
directory:
In the S-parameter solution request, all the ports are added, and the
characteristic impedance for each port is set to 50 ohms.
Restriction: All ports of interest need to be added to the S-parameter request, and all ports in the request must be set active.
The アプリケーションマクロ calculates the complete interference
matrix for all ports in the request.
Using the Application Macro
Execute the アプリケーションマクロ in POSTFEKO to determine the interference matrix for the multiport S-parameter calculation.
