US Patent 9065162 In-phase H-plane waveguide T-junction with E-plane septum

In an example embodiment, an in-phase H-plane T-junction can comprise: a first waveguide port; a second waveguide port; a third waveguide port, wherein the third waveguide port can be a common port; and an E-plane septum. The first, second, and third waveguide ports can be in the H-plane and can be each connected to each other in a T configuration. The T-junction can be configured such that microwave signals in a first band can be in-phase with each other at the first and second waveguide ports, and microwave signals in a second band can be in-phase with each other at the first and second waveguide ports. The H-plane T-junction can be at least one of a power combiner and a power divider.
