Microstrip line coupler for microwave transmission

摘要

Line coupler comprising at least two coupling lines (510) formed by microstrips, comprising an insulating substrate (20) on one side of which an earth conducting layer (30) is applied and on the other side of which at least one central conductor for transmission of the signal is applied, said central conductor comprising at least two conducting layers (111a;111b) which are separated by a dielectric layer (112) and are connected together by a longitudinal, interconnecting, conducting rib (214).
