Title: Paul H Carr: Innovator in Photoconductive Antenna Technology
Introduction
Paul H Carr is a notable inventor based in Bedford, MA (US), recognized for his contributions to the field of photoconductive antennas. With a total of 4 patents to his name, Carr has made significant advancements in antenna technology that leverage the properties of semiconductor materials.
Latest Patents
Carr's latest patents include innovative designs such as the "Spatially Light Modulated Reconfigurable Photoconductive Antenna." This invention involves creating a reconfigurable photoconducting antenna on a semiconductor substrate. At equilibrium, the semiconductor remains semi-insulating, functioning as a dielectric. When illuminated, free carriers are generated, allowing for the creation of a conductive region that acts as the antenna's radiating element. The pattern of illumination directly influences the antenna's radiating pattern, which can be dynamically adjusted using a digital micromirror device (DMD™). This device operates through a standardized digital interface, enabling rapid pattern switching in approximately 20 microseconds.
Another significant patent is the "Three Dimensional Reconfigurable Photoconductive Antenna Array Element." This invention features tandemly positioned electrically biased semiconductor members that radiate microwave energy in response to an excitation light beam with two wavelengths. By simultaneously biasing both members, the projected microwave beam can be made narrower and more directional. This design simplifies the excitation process, allowing a single light beam to activate both members effectively.
