Title: Frédéric Devillers: Innovator in Antenna Technology
Introduction
Frédéric Devillers is a notable inventor based in Nice, France. He has made significant contributions to the field of antenna technology, holding two patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is the Multi-band printed dipole antenna. This invention relates to a printed antenna that comprises a dielectric substrate supporting feeder lines and first and second T-shaped dipoles of different sizes for dual-band operation. Each dipole includes a stem and two radiating arms separated by a coupling slot made in the stem. To enhance the compactness of the antenna, the stems are partly superimposed, and the coupling slots are aligned. A decoupling cut-out is made in the second dipole to uncover the coupling slot of the first dipole, thanks to their superposition. The substrate can consist of one, two, or three layers, and plural antennas can form an antenna network used as a base element in one-dimensional or two-dimensional networks.
Another significant patent is the Electromagnetic probe. This probe features at least one assembly that includes a coaxial type connection, a ground plane connected to the outer sheath of the coaxial connection, and a reflector cone placed facing the ground plane. The reflector cone is shaped to define impedance that is at least substantially constant along its profile, while being electrically isolated. A dielectric medium is interposed at least in part between the reflector cone and the ground plane.
