About Waveguide Sweep Bends
What is a waveguide sweep bend?
A waveguide sweep bend (also known as a swept bend), is a 2-port transmission line device. It is curved or bent in a particular orientation that allows the waveguide to align with another RF component or transmission line. It is critical to have the correct type, configuration, and angle of bend, as it regulates the loss and reflections within a system.
What are they used for?
Typically, they are utilized for the purpose of directing signals propagating through a waveguide system in a specific direction. They allow the change in direction of a signal within a waveguide with minimal loss, reflection, and distortion of the electric and magnetic fields.
What are the two types of sweep bends?
E-Plane Bend: changes or distorts the E-Field (Electric Field) of the propagating signal.
H-Plane Bend: changes or distorts the H-Field (Magnetic Field) of the propagating signal.
What are typical bend angles for waveguide sweep bends?
Typical angles include 30, 45, and 90 degrees. At Microwave Techniques, we typically manufacture 90° waveguide sweep bends. However, other angles or bend radii can be readily supplied.
