Title: Ronald M. Kates and His Microwave Antenna and Sensing Patents.

Introduction

Ronald M. Kates is an inventor based in Newbury Park, California. His work includes patented technologies for multi-band antennas and microwave sensing of road-surface conditions. He is associated with Hughes Electronics Corporation and holds 2 patents.

Latest Patents

Kates’s listed patents address antenna design and the detection of materials on road surfaces.

“Slot Fed Multi-Band Antenna” describes a laminated microstrip antenna circuit with a radiating slot ring and a stripline feed. A micromachined electromagnetic switch changes the antenna member’s length, enabling resonant frequencies that correspond to those radiated by the ring slot.

“Dielectric-Loaded Surface-Condition Sensor and Method” describes a microwave sensor embedded in a road surface. It uses reflections from a dielectric member to distinguish conditions such as air, water, and ice. The frequency of an amplitude minimum in the return signal can also be used to determine ice thickness.

Career Highlights

Kates’s listed inventions apply microwave and antenna technologies to two distinct purposes: producing multi-band antenna responses and identifying surface conditions. His work at Hughes Electronics Corporation provides the company context for these innovations.
