Substrate Parameters

εr: Relative permittivity of the substrate.

Tanδ: Loss tangent of the substrate. This parameter is used for
the loss calculations. The higher the value, the larger the loss.

Rho: Conductor resistivity relative to copper. This parameter is
used for the loss calculations. When in doubt, use 1 for copper, .946 for silver,
or 1.45 for gold.

Height: Height of the substrate.

Thickness: Thickness of the microstrip conductor. This can be set
to zero, but the calculated loss will not include conductor losses.

Frequency: Frequency at which the microstrip transmission line
is analyzed or synthesized.

Loss is calculated as a combination of dielectric loss and conductor
loss at the analyzed/synthesized length. If the conductor thickness is set to zero,
the loss will only include the dielectric loss component.
