Research on Conversion Method of Multi Beam Waveguide Based on Euler Angle
The design of multi beam waveguides is greatly constrained by factors such as layout space,satellite assembly,and aesthetics neatness.Generally,it is a multi-layer and multi-column form,with a direction parallel to the satellite plate.As the starting port of multi beam waveguide,multi beam antenna usually has multiple angles with the satellite plate,and the normalization of waveguide ports has become a challenge in waveguide layout stage on the basis of the principles of plane rotation and three dimensional rotations,Euler angle is proposed to handle alignment of multi beam waveguide port,which is defined by internal rotation.Rotating along the ZYX axis is adopted,curved and twisted waveguide is designed by reference to rotation angle,which meets the alignment of multi beam waveguide.Connected in a predetermined order,then appropriate position between the output port of waveguide and satellite plate is achieved.Normalization of waveguide ports is solved,which lays the foundation for the design of multi beam waveguide.The correctness of proposed method is verified by high throughput satellite,which has important ref-erence value for waveguide layout of high throughput satellites using multi beam schemes.
