Title: Innovations of John D Norgard

Introduction

John D Norgard is a notable inventor based in Colorado Springs, CO (US). He has made significant contributions to the field of antenna technology, particularly with his innovative designs that enhance signal reception and transmission.

Latest Patents

Norgard holds a patent for a "Miniature phased array antenna system." This invention employs a substrate with a high dielectric constant, featuring a plurality of antenna elements located on its surface. A superstrate, also with a high dielectric constant, covers these antenna elements. The unique design allows the superstrate to function as a dielectric lens, controlling the phase relationship of signals received by the antenna elements. This advancement enables a reduction in the physical spacing between antenna elements while maintaining spatial diversity in phase for signals arriving from various directions. Consequently, the antenna array can be significantly smaller than conventional phased array antennas while achieving similar phase relationships. The electronic circuitry connected to each antenna element applies complex weights to received signals, facilitating the reconstruction of desired signals and the deconstruction of undesired ones. Additionally, temperature-controlled SAW filters in the circuitry ensure stability in group-delay and phase-offset.
