Title: François Grange: Innovator in Magnetic Conductors and Antenna Technology
Introduction
François Grange is a notable inventor based in Moirans, France. He has made significant contributions to the fields of magnetic conductors and antenna technology. With a total of 2 patents, his work is recognized for its innovative approach and practical applications.
Latest Patents
François Grange's latest patents include an artificial magnetic conductor and a planar antenna with a widened bandwidth. The artificial magnetic conductor features a surface impedance greater than 100Ω and includes a ground plane along with a frequency-selective surface. This surface is designed to be transparent for certain wavelengths while being reflective for others. The frequency-selective surface consists of an array of conductive resonant elements arranged in at least two different directions parallel to the ground plane. Each resonant element incorporates a sub-layer of ferromagnetic material with a relative permeability greater than 10 at a frequency of 2 GHz, and a thickness less than the skin thickness of the ferromagnetic material. The planar antenna, on the other hand, comprises at least one first conducting element positioned above an earth plane, separated from it, and is equipped with means to excite two distinct orthogonal resonant modes. This antenna is particularly applicable to mobile communications terminals.
