Waveguide Bends

Dolph Microwave offers a standard product line waveguide bends. It is divided into sweep bend and mitered bends covering waveguide sizes WR10 thru WR770. All can be offered both in E-bends and H-bends based on system application. Multi-degrees, additional sizes, configurations and combinations are available on request.

Difference of Each Bend Type

E bend

Waveguide E bend is to change the electric field so that the waveguide is bent in the required direction which is to avoid reflections. This type of bend requires the radius must be greater than two wavelengths.

H bend

Waveguide H-bend is very close to the E bend, but it distorts the H or magnetic field which only happens to the bend around the thinner side of the waveguide.

Sharp E bend

In some assemble limited conditions, a much shorter or sharper bend is required. This can be accomplished in a slightly different method of production technology. Using a 45° surface the reflections occur in such a way that the fields are not disturbed.

Sharp H bend

Sharp waveguide H bend is the same as the sharp E bend, the only difference is it is aimed to affect the H field rather than the E field.
