Dipole on thin substrate using local multilayer

Integral Equation Solver Examples

General Description

This example shows the S-parameter calculation of a dipole antenna in presence of a thin layered structure which is modeled using the local multilayer functionality.

Structure Generation

The dipole is generated by two PEC sheets using primitive shapes. A faceport is placed between both sheets. In addition an infinitely thin sheet is generated for the thin substrate. By using "Thin panel" type material multiple layers with finite thickness will be considered.

Solver Setup

For the thin layer representation no mesh for the "Thin panel" is created. To ensure the field calculation considers the defined layer stackup for the antenna the following steps are executed.

Create sheet with layer stackup as "Thin panel"material.
Thin panel definition requires to attach a WCS. Otherwise it will be ignored.
Use discrete face ports for excitation.
Use open (add space) boundary conditions.
Thin panel material is not considered automatically. Create a mesh group with local mesh properties to define a local multilayer.
Put all parts of the antenna which should be in the local multilayer setup (including the thin panel sheet ) into this mesh group. Ports are handled automatically.
Thin panel will then be considered for the field calculation within metallization of the local multilayer.
Optional: Define offset for the antenna structure in reference to the defined WCS.

Post Processing

S-parameter results can be found in the navigation tree under 1D Results.
