Curved waveguide is the basic element in waveguide feeder system, which can be divided into three categories: E-plane / H-plane circular arc curved waveguide, E-plane / H-plane angle cut curved waveguide and composite curved waveguide.Angle cut curved waveguide can be applied to the situations of arm length, large waveguide, narrow band width and low power. The standard bending angle is 90 °, and other bending angles can be customized. XEXA TECH arc waveguide bend is manufactured by precision machining technology to ensure high quality and robustness It is very suitable for radar antenna system, laboratory test device, microwave radio, satellite communication and other applications requiring low insertion loss and low return loss. The overall dimension, flange, material, surface treatment method and electrical parameters of the waveguide bend can be customized according to user requirements.
