Hi Mumin,

MATLAB's Antenna Toolbox can simulate the radiation pattern of antennas installed on platforms made of both dielectrics and metals. The process involves:

Select the antenna model and specify the properties of dielectrics and metals.
Create a 3D model of the platform, assigning appropriate materials to different parts.
Discretize the model into a finite element mesh for simulation.
Use numerical methods like MoM or FEM to compute the electromagnetic fields and radiation pattern.
Examine the radiation pattern and other performance metrics, utilizing MATLAB's visualization tools.
Adjust design and materials based on simulation outcomes for optimal performance.

This toolbox is designed for iterative design and analysis, allowing for detailed study of how platform materials affect antenna performance.

Thanks for the answer.

May I kindly ask what this bold sentence mean which is taken from the link below ?

Note: installedAntenna only models pure metal structures.

https://uk.mathworks.com/help/antenna/ref/installedantenna.html

For instance, if i want to simulate installed antenna performance for a car which is made of metals and dielectric components, Then, MATLAB cannot simulate a CAD file which is made of metals and dielectrics.

This is the messeage I got.
