Pyrolytic boron nitride as a microstrip substrate material

Abstract

The use of pyrolytic boron nitride (PBN) as a substrate material for microstrip integrated electrical structures operating at microwave frequencies is investigated in this paper. It has been found that PBN has potential as an alternative substrate material. The electrical aspects of PBN will first be detailed, followed by a discussion of PBN's material properties affecting the construction and performance of single and coupled transmission line structures on PBN.
