Title: Charles Ngounou: Innovator in Microstrip Antenna Technology
Introduction
Charles Ngounou is a notable inventor based in Les Ulis, France. He has made significant contributions to the field of antenna technology, particularly through his innovative designs of microstrip antennas. With a total of 2 patents to his name, Ngounou's work has implications for modern telecommunications.
Latest Patents
Ngounou's latest patents include a multifrequency microstrip antenna and a device incorporating this antenna. The multifrequency microstrip antenna features two zones connected to a short-circuit made up of two conductive strips. These zones are designed to be sufficiently decoupled from each other, allowing for the establishment of two resonances in distinct areas formed by the zones. Each resonance is approximately of the quarter-wave type, with an electric field node fixed by the short-circuit. This invention is particularly applicable to portable telephones and their base stations.
Another significant patent is a quarter-wave antenna that consists of a patch and a ground formed on opposite surfaces of a substrate, connected by a short-circuit. A coupling strip enters the patch via the short-circuit and extends between two lateral slots, which are designed to be narrow enough to allow a lateral coupling effect to contribute to the excitation of the antenna. This invention also finds its primary application in mobile telephones.
