Planar orthomode transducer

Abstract

A planar orthomode transducer comprises a substrate integrated resonator, two substrate integrated waveguides connected to the substrate integrated resonator, a dual polarized metal waveguide and a printed circuit board where the substrate integrated resonator and the substrate integrated waveguides are provided, wherein the substrate integrated resonator further comprises a slot aperture in one of metallization layers, and the dual polarized metal waveguide is mounted on a surface of the printed circuit board in an area of the slot aperture of the substrate integrated resonator, wherein the substrate integrated resonator is a nonfundamental orthogonal mode resonator. This enables widening of frequency band of the planar orthomode transducer, reducing of insertion losses, rise of the polarization diversity and providing for a standard dual polarized output waveguide serving for connecting the device with an antenna of various types.
