  • Broad band quad ridged polarizer
    Patent number: 6097264
    Abstract: A broad band waveguide polarizer having four axial ridges, one on each wall of the waveguide, is disclosed. The axial ridges are configured to provide different phase velocities for the orthogonal signal components of a linearly polarized input signal. The dimensions of the ridges are selected such that the net phase difference between the signal components is about 90 degrees at a predetermined signal frequency. The quad ridge polarizer may be manufactured as an integral die cast device.
