INHOMOGENEOUS DIELECTRIC MEDIUM HIGH-SPEED STRIPLINE TRACE SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18448598 titled 'INHOMOGENEOUS DIELECTRIC MEDIUM HIGH-SPEED STRIPLINE TRACE SYSTEM

Simplified Explanation

The patent application describes a system for high-speed signal traces in a medium with varying dielectric properties.

  • The system includes two ground layers and two dielectric layers.
  • The first dielectric layer is adjacent to the first ground layer.
  • The second dielectric layer has a different dielectric constant and is thicker than the first dielectric layer.
  • A first differential trace pair is located between the first and second dielectric layers.
  • The trace spacing of the first differential trace pair is equal to or smaller than the thickness of the first dielectric layer.
  • The first differential trace pair transmits signals and generates a magnetic field.
  • The trace spacing prevents the magnetic field strength from exceeding a threshold at a second differential trace pair located next to the first differential trace pair.


Original Abstract Submitted

An inhomogeneous dielectric medium high-speed signal trace system includes a first and second ground layer. A first dielectric layer is located adjacent the first ground layer. A second dielectric layer has a different dielectric constant and a greater thickness than the first dielectric layer, and is located between the first dielectric layer and the second ground layer. A first differential trace pair is located between the first dielectric layer and the second dielectric layer, and includes a trace spacing that is less than or equal to a thickness of the first dielectric layer. The first different trace pair transmit signals and, in response, produces a magnetic field, and the trace spacing prevents a magnetic field strength of the magnetic field from exceeding a magnetic field strength threshold at a second differential trace pair that is located adjacent the first differential trace pair.
