The developed polarizer converted the linear vertical polarization (VP) or horizontal polarization (HP) of antenna to linear inclined. The polarizer consist of four printed circuit board made of Rogers RO4350B and four layers of foam plastic ПС-1-100. Thickness of Rogers RO4350B is 0,254 mm, thickness of foam plastic ПС-1-100 is λв/12,5 (where λв – wavelength on upper frequency). Printedcircuit pattern is multitude of printing lines. The width of printing lines (t) is less than λв/25. Distance between the printing lines is 3t. The printing lines into different layer disposed on-the-miter 11°, 22°, 33°, 45° relative to broad dimension of waveguide. The layer of foam plastic ПС-1-100 located before the first printing layer for matching. Thickness of matching layer is 0,2λв.

Full-wave 2 of polarizer 3D model were carried finite-integratiom technique method. The rated patterns of antenna without polarizer and with polarizer and gain without polarizer and with polarizer for three frequency are presented.

VP are to linear inclined by use of polarizer converted. Horizontal component of electric field vector are emerged. Polarizer work in wide-ranging of frequency. Maximum deviation of breadth of pattern is 2,1°.
