Title: James Robert Howard and Fractal Structures for Reducing Electronic Noise

Introduction

James Robert Howard is an inventor associated with Reno, Nevada. His patent work addresses a challenge in printed circuit board design: reducing radiated electromagnetic emissions, or electronic noise, from power and ground planes. The supplied information identifies him as a man and lists one patent.

Latest Patents

Howard’s listed patent, “Capacitive Power and Ground Plane Structure Utilizing Fractal Elements for the Reduction of Radiated Emissions,” describes using fractal patterns in a capacitive power-and-ground-plane structure to reduce or eliminate radiated noise. The patterns may be placed along the edges of the ground plane, the power plane, or both, and may also be incorporated into circuit lines or other conductive elements on the board.

The design uses the fractal structures to absorb or reject frequencies generated during device operation, supporting the planes’ capacitive effect. The patent describes reducing noise across the X, Y, and Z axes without surface bypass capacitors or conventional approaches such as edge plating and via-hole edge stitching.
