Abstract
The invention features a method of fabricating a printed circuit board with low dielectric materials using a modular technique. Sub-assemblies are first constructed, tested, and then subsequently incorporated into the final circuit board assembly which has a triplate geometry. Dielectric materials are chosen which enhance the performance of the circuit board.
