Differential phase-shifter operating in a wide frequency band, with constant differential phase shifting. This device is characterized by the fact that it produces a differential phase shift between two perpendicular polarizations, with constant frequency. This way, differential phase shifters with the desired flatness in the band can be obtained, either of 180 DEG (polarizers for systems of linear polarization) or of 90 DEG (polarizer for transforming the circular polarization into linear polarization and vice versa). Such a phase shifter can be used generally in antenna systems.
