A compact dual-polarization planar power splitter comprises at least four asymmetric orthomode transducers (OMTs) connected in an array suitable for being coupled in-phase to a dual orthogonal polarization feed source via two power distributors mounted perpendicularly in relation to one another, each power distributor comprising at least two lateral metal waveguides disposed parallel to one another, and a transverse metal waveguide coupled perpendicularly to the two lateral metal waveguides and four ends of the lateral waveguides coupled respectively to the four asymmetric OMTs.

A power splitter comprises at least two mutually parallel lateral waveguides with rectangular cross-section and a transverse waveguide with rectangular cross-section comprising two opposite ends respectively connected to the two lateral waveguides. The two lateral waveguides are oriented along a direction Y and mounted flat with their large side parallel to a plane XY, the transverse waveguide is oriented along a direction X perpendicular to the direction Y and mounted edgewise with its small side parallel to the plane XY, and each lateral waveguide is coupled to the transverse waveguide by a tee coupler in the E-plane with embedded junction, the two ends of the transverse waveguide being respectively embedded in each lateral waveguide, at the center of the said respective lateral waveguide.
