Stripline Resistance
Stripline Resistance Model
DC resistance of Stripline conductors is:
where
Units: Ohms
AC resistance of Stripline conductors is:
where
Units: Ohms
Skin Depth is:
Description
Resistance calculated using this tool includes both dc and ac resistance of stripline conductors. At low frequencies, where skin depth is greater than conductor width and thickness is greater than ground plane thickness, ac resistance is approximately the same as the dc resistance. As frequency increases, ac resistance increases.
Assumptions and Limitations
Dimensions are in meters.
Trace conductor is assumed to have uniform circular cross section and to be uniformly spaced above the ground plane over its length.
Separation between the conductors is assumed to be large enough that proximity effect may be ignored.
