Wilkinson Coupler Integrated into a Printed Circuit and Microwave Device Comprising Such a Coupler

摘要

A Wilkinson coupler mounted on a printed circuit comprises a first access port connected to a second access port and to a third access port by way of two metallic transmission lines of the same length and a load resistor mounted in short-circuit arrangement between the second and third access ports, characterized in that the load resistor is constituted of three adjacent independent resistors linked together. The coupler applies notably to the field of satellite antennas and more particularly to antenna beamforming arrays.
