The left part of the screen shows input data along with an illustration. A strip of width w, with sigma sub c equals infinity is placed on a substrate of height h, sitting on a ground plane with sigma sub c equals infinity. The parameters for the substrate are, epsilon sub r equals 9.8, and sigma equals 0. The following input parameters are specified in menu items:

Strip width, w equals 1.276 millimeters

Substrate thickness, h equals 0.635 millimeters

Frequency, f equals 1.794 E9 hertz

The right part of the screen shows an output signal for effective relative permittivity as a graph along with output data. The graph plotting epsilon sub r, e f f versus w in millimeters shows a curve that starts on the y-axis and moves near horizontal in an upward slope. A point is marked on the curve approximately at (2.0, 7.0).

The output data are as follows:
