Title: The Innovations of Jacques Espaignol
Introduction
Jacques Espaignol is a notable inventor based in Paris, France. He has made significant contributions to the field of millimeter wave technology, holding three patents that showcase his innovative spirit and technical expertise.
Latest Patents
Espaignol's latest patents include a process for the manufacture of millimeter wave sources of the module type. This invention describes a batch production process that involves a basic metallic support with a diode in the form of a semiconductor chip. The diode is soldered onto a projection of the support and is surrounded by a dielectric substance. This medium extends up to half a wavelength on the same support, with metallization covering the surrounding medium and connecting to the top of the chip via a metallic block. The first embodiment of this process focuses on the central part of the module, while the second embodiment allows for the collective production of the entire module.
Another significant patent is the solid-state millimeter wave source comprising a directive antenna. This source is adjustable in power and frequency and is designed as a cylindrical waveguide. One end features a movable piston, while the other end is equipped with a directive antenna, typically a radiating horn. A cylindrical waveguide branch is tapped between the ends, allowing a sub-assembly carrying a radiating module with an oscillating diode to slide. The position of this module influences the power and frequency of oscillation, while the movable piston regulates the power emitted by the radiating horn.
