Claim:
A waveguide corner comprising: a first waveguide having a first pipe axis, the first waveguide including: a pair of opposing first walls, the pair of opposing first walls having a longitudinal dimension perpendicular to the first pipe axis, a pair of opposing second walls having a transverse dimension perpendicular to the first pipe axis, the pair of second walls positioned at respective ends of the pair of first walls and connecting the pair of first walls, and an end wall extending between the pair of opposing first walls and the pair of opposing second walls so as to close one end of the first waveguide; and a second waveguide having a second pipe axis and connected to the first waveguide in a bent state, the second waveguide including: a pair of opposing third walls having a longitudinal dimension perpendicular to the second pipe axis, and a pair of opposing fourth walls having a transverse dimension perpendicular to the second pipe axis, the pair of fourth walls positioned at respective ends of the pair of third walls and connecting the pair of third walls, wherein an end face of the second waveguide is open to one of the first walls of the first waveguide, wherein one of the third walls of the second waveguide extends along the first pipe axis of the first waveguide, wherein one of the third walls of the second waveguide is in the same plane as one of the second walls of the first waveguide, wherein one of the fourth walls of the second waveguide is in the same plane as the end wall of the first waveguide, and wherein the waveguide corner is configured so as to propagate a signal from the first waveguide to the second waveguide without a step between the first waveguide and the second waveguide.
