Abstract
In a reciprocal microwave phase shifter of microstrip technology, a Ferrite substrate carries, on one side, a ground plane (PM) and, on the other, a microstrip line (LM). The lateral branches (CG2 and CD2) cooperating with a base (CC) to define a magnetic circuit come into direct contact with the Ferrite substrate (SF), be being, for example, equipped with a recess (ED2) in line with the passage of the microstrip line (LM).
