History
-------

Stripline was invented by Robert M Barrett of the US [Air Force Cambridge Research Center](/wiki/Air_Force_Cambridge_Research_Center "Air Force Cambridge Research Center") in the early 1950s. Air stripline under the registered mark *Stripline* was first manufactured commercially by Airborne Instruments Laboratory (AIL) in the form of suspended stripline. However, *stripline* has since become a generic term for that structure with any dielectric. The unadorned term *stripline* would now likely be assumed to mean stripline with a solid dielectric. Early on, stripline was the planar technology of choice, but has now been superseded by [microstrip](/wiki/Microstrip "Microstrip") for most general purpose applications, especially mass\-produced items.Oliner, pp. 557–558


Why has the term 'stripline' become generic?
