White Paper: Millimeter-Wave Printed Circuit Board Developments - Improvements For Mechanical Packaging And Electrical Requirements

Millimeter applications place heightened and unique requirements on circuit board laminates used as transmission lines or as antennas. Historically, applications were low volume. Recent growth of millimeter applications, such as ACC (adaptive cruise control) and side lane changing sensors for standard, high volume, affordably priced vehicles, or commercial millimeter communication systems, has driven circuit board laminate fabricators to innovate materials. This article explores advancements in millimeter-wave circuit boards and the technical requirements placed on materials.
