Patent ID: 7804381

Claim:
A waveguide apparatus for use with received data, said waveguide apparatus including an inlet into a first channel into which received signals pass, said received signals including two orthogonal components of at least one polarization, said first channel having located therein a first deflection means which causes at least a first component of said polarization to be deflected to leave said first channel through a first aperture in the first channel into a second channel, and a second deflection means which causes at least a second component of said polarization to be deflected to leave said first channel through a second aperture in the first channel into a third channel, wherein said components are guided through said second and third channels to outlets in substantially the same phase wherein distances travelled by said first and second components of said polarization between entering the waveguide apparatus at the inlet and leaving the waveguide apparatus at said respective outlets are substantially the same.
