Introduction

Rene Le Dain is a notable inventor based in Cesson Sevigne, France. He is recognized for his contributions to the field of microstrip technology, particularly through his innovative patent.

Latest Patents

Rene Le Dain holds a patent for a wide band directional coupler for microstrip lines. This invention features a microstrip line section whose conductive core is coupled to the core of the main line over a length of .lambda./4, where .lambda. represents the wavelength in a mid portion of the desired pass band. The design includes a first fraction that runs parallel to the main line at a small distance to ensure tight coupling, and a second fraction that diverges from the main line and is closed on a matching impedance. The free end of the first fraction connects to the load and has an extension projecting over a length less than .lambda./16, forming a microcapacitor that taps energy from the main line.
