In-phase h-plane waveguide t-junction with e-plane septum

An in-phase H-plane T-junction comprising:

• a first waveguide having a first waveguide port at a first end of said first waveguide and an H-type T-junction with an E-plane septum at a second end of the first waveguide, wherein the E-plane septum is a full width E-plane septum across the width of the first waveguide and divides the first waveguide into a top waveguide portion and a bottom waveguide portion, wherein the output of the first waveguide port faces in a first direction, and wherein the first waveguide port is in a first plane;
• a second waveguide port the output of which faces in a second direction, wherein the second waveguide port is in a second plane, wherein the second waveguide port is connected to a second waveguide that connects to the bottom waveguide portion;
• a third waveguide port the output of which faces in a third direction opposite the second direction, wherein the third waveguide port is in a third plane, and wherein the first, second and third planes are parallel to each other, and wherein the third waveguide port is connected to a third waveguide that connects to the top waveguide portion;
• wherein the T-junction is configured such that microwave signals in a first band are in-phase with each other at the second and third waveguide ports, and microwave signals in a second band are in-phase with each other at the second and third waveguide ports;
• and
• wherein the H-plane T-junction is at least one of a power combiner and a power divider.
