Microstrip Wizard
MENU: Tools â Transmission Line Wizards â Microstrip Line
MODULE(S): EM.Tempo, EM.Picasso, EM.Ferma
FUNCTION: Creates the parameterized geometry of a microstrip line segment of a specified characteristic impedance on a conductor-backed single-layer dielectric substrate in the project workspace
NOTES, SPECIAL CASES OR EXCEPTIONS: In EM.Tempo and EM.Picasso, this wizard creates a one-port open-ended microstrip transmission line segment. In EM.Ferma, it sets up a 2D solution plane for quasi-static analysis of the microstrip transmission line. The width of the microstrip line is determined based on the specified characteristic impedance. It may be replaced by a numeric value instead.
