Micro-strip gap capacitance data

It is interesting to note the lack of sufficient measurement data on the capacitance of a micro-strip gap. Based on conventional models, a micro-strip gap yields a series capacitance and two shunt capacitors for each side of the gap, thus forming a pi – network. However, measured data for these values of capacitance is not freely available. A recent study on the micro-strip gap model is constrained by this non-availability of data. IEEE has some data published in 1972 but this is restricted to a fixed dielectric constant and width/height ratio. Anyone with information on publicly available measured data for these capacitors please leave a comment.
