Windscreen Antenna on an Automobile

Calculate the input impedance of a windscreen antenna constructed from wires. The windscreen consists of a layer of glass and a layer of foil.

Figure 1. A 3D view of an automobile and windscreen antenna.

The windscreen antenna (wires) can be embedded in the windscreen layers or placed on the surface of the windscreen.

The windscreen curvature reference can consist of multiple layers consisting of different media. Its mesh elements are not part of the solution in terms of computational resources.
