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.
Waveguide bends can be divided into E bend, H bend, sharp E bend and sharp H bend
Each type of bend is the same function which is to enable the signal to transmit correctly and with the minimum of interference to the fields and the overall signal.
The most common bend requirements are 90° and 45°. But other requirements for waveguide bends can also be offered based on requirements.
