Title: Francedillaois Lepennec: Innovator in Microstrip Antenna Technology
Introduction
Francedillaois Lepennec is a notable inventor based in Porspoder, France. He has made significant contributions to the field of antenna technology, particularly in the development of multifrequency microstrip antennas. With a total of 2 patents to his name, Lepennec's work has implications for modern telecommunications.
Latest Patents
Lepennec'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. The resonances are approximately of the quarter-wave type, each having an electric field node fixed by the short-circuit. This innovative design is particularly applicable to portable telephones and their base stations.
Another patent involves 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 through the short-circuit and extends between two lateral slots, allowing for resonance excitation. The lateral slots are designed to be narrow enough for a lateral coupling effect to contribute to the antenna's excitation from the edges of the strip. This invention also finds its primary application in mobile telephones.
