填充位准雷达之模式转换器;MODE CONVERTER FOR FILLING LEVEL RADAR

摘要

本发明揭示一种用于一位准雷达(12)之模式转换器(30)，其包括：一输入管线(20)，其用于将一高频率信号引入至该模式转换器中；一螺旋结构(58)，该输入管线(20)之一导体(46)突出至该螺旋结构(58)中且该螺旋结构(58)包括复数个螺旋形电导体(68)；及一波导(49)，其封围该螺旋结构(58)。该螺旋结构(58)经组态以将来自该输入管线(20)之该高频率信号转换成该波导(49)中之一H01模式。; a helix structure (58) into which a conductor (46) of the input line (20) projects and which comprises a plurality of helical electrical conductors (68); and a waveguide (49) which encloses the helix structure (58). The helix structure (58) is configured to convert the high-frequency signal from the input line (20) into an H01 mode in the waveguide (49).
