How it affects the antenna design?

Miguel Ferrando-Rocher

Dear Rakesh,

Create a new "Characteristic Mode Analysis" (CMA) setup in the "Simulation" tab.

Define the frequency range, simulation accuracy, and solver options.

Run the simulation.

Once the simulation is complete, go to the "Results" tab and select "CMA Eigenmode Results".

Select the mode you are interested in and then click on the "Far Fields" tab to visualize the modal far-field pattern.

To visualize the surface current distribution, go to the "Fields" tab and select "Currents".
