Title: Jacques Legendre: Innovator in Microwave Technology
Introduction
Jacques Legendre is a notable inventor based in Paris, France. He has made significant contributions to the field of microwave technology, holding a total of 3 patents. His work focuses on innovative solutions that enhance the functionality and efficiency of microwave systems.
Latest Patents
One of Jacques Legendre's latest patents is a microwave phase shifter circuit. This invention discloses microwave phase shifter circuits that achieve phase shifts of elementary values and whole number multiples of these values. The phase shifter circuit utilizes strip lines arranged in a candlestick form on one face of a substrate, while a slot line is arranged on the opposite face. The branches of the candlestick differ in length by b/4, where b represents the wavelength. The ends of these branches can be short-circuited or not, using diodes that can be forward or reverse biased. Another significant patent is a 180-degree phase shifter for microwaves supplied to a load, such as a microstrip line. This microstrip line is formed on a dielectric substrate and is electrically coupled to a slot line with the help of supplemental conductors. These conductors include a pair of diodes that are selectively conductive, allowing for a 180-degree phase shift of oscillations transmitted by the slot line to a load when the microstrip line is energized.
