How to add concentrated components to adjust impedance matching in CST [Copy link]

Just as the title says.

Due to size limitations, it is necessary to add lumped elements (capacitors in parallel, inductors in series) at the feed point to adjust the matching. Can anyone tell me how to achieve this in cst?

I have tried the following scenarios and all failed.

1. The feed source is connected in series with the inductor, indicating that there is half of the metal between the feed source and the inductor;

2. The feed source, inductor and capacitor are all connected in series between the antenna and the floor, and the simulation stops automatically when the simulation accuracy cannot be achieved;
