The best "free" transmission line calculator I've found is from
Applied Wave Research (http://www.appwave.com/). It has given
reasonable results. While it doesn't cover quite the range of
geometries of some of the more sophisticated <not free> software,
it handles CPW, CPWG. slotline, stripline and microstrip.
