Microstrip Capacitance – Microstrip Calculator Capacitance Calculators
Microstrip Capacitance Model
Capacitance between the upper conductor and ground plane is:
The capacitance calculated using this tool is the capacitance between a flat conductor and the ground plane over the conductor length.
Assumptions and Limitations
Dimensions are in meters.
Ground plane is assumed to be perfectly conducting and of infinite extent.
Conductor is assumed to have zero thickness and to have uniform height above ground.
Conductor and ground plane are assumed to be separated by a homogeneous medium having permittivity and permeability.
Permeability of free space: H/m
Permittivity of air: F/m
Speed of light in a vacuum: m/s
