Mechanical phase shifter which from an external feed signal obtains several signals out of phase with each other, each one of which is applied to an antenna of an array, so that the result of the interference of the radiated fields provides a radiation pattern. The object of the invention is to obtain a greater range of pointing angles, achieved by protrusions or screws that act as capacitors or short-circuits that allow suppressing the higher modes generated in the phase shifter, as well as preventing part of the mutual coupling between the phase shifter L-lines. In addition, due to the greater length of the L-lines, these are reinforced by a protrusion perpendicular to the greater length of the line located on the outer edge of each L-line, and in addition they are provided with supporting means for the L-lines which minimise the vibrations, sag and deformations. The L-lines also increase the frequency at which higher modes appear.
