Abstract
A dual polarized waveguide device includes a first waveguide that defines a first linear signal propagation path, a second waveguide that defines a second linear signal propagation path that is parallel to the first linear signal propagation path, and a polarization selective coupling interface coupling the first and second waveguides, the polarization selective coupling interface being configured to enable horizontally polarized signals to pass between the first and second linear propagation paths and prevent vertically polarized signals from passing between the first and second linear propagation paths.

A dual polarized waveguide device comprising:
- a first waveguide that defines a first linear signal propagation path
- a second waveguide that defines a second linear signal propagation path that is parallel to the first linear signal propagation path;
- and
- a polarization selective coupling interface coupling the first and second waveguides, the polarization selective coupling interface being configured to enable horizontally polarized signals to pass between the first and second linear propagation paths and prevent vertically polarized signals from passing between the first and second linear propagation paths.
A method of guiding cross-polarized signals comprising:
- guiding the cross-polarized signals in a first linear waveguide path that is parallel to a second linear waveguide path;
- and
- at an interface between the first linear waveguide path and the second linear waveguide path, permitting horizontally polarized signals of the cross-polarized signals to couple from the first linear waveguide path to the second linear waveguide path and preventing vertically polarized signals of the cross-polarized signals from coupling from the first linear waveguide path to the second linear waveguide path.
