Multilayer/Stripline Design Considerations Introduction
Brief History of Stripline Design
1964: Matthais, Young and Jones “bible” of microwave coupled circuits published
Interim: PTFE substrates used in radome apps-suspended stripline and
lumped element design realizations only
Stripline on soft substrates developed on Long Island, NY
1974: Harlan Howe Jr “Stripline Circuit Design”
1970’s: Woven glass reinforced PTFE laminates introduced
1990’s: Development of 2-d and 3-d EM simulation software
(ADS, Microwave Office, HFSS, etc.)
Today: Reliable PTFE/multilayer materials and techniques allow for empirical
realizations of simulated performance
