Nrd guide converter and connected structure of dielectric and conductor

摘要

In order to realize with a low loss a hybrid structure in which an NRD guide is used for a transmission part and a microstrip line is used for a circuit element loading part, the present device includes: a dielectric waveguide ( 1 ) which is sandwiched between parallel conductor plates and has a gap which is less than a ½ wavelength; a microstrip line ( 4 ) which is provided on a side surface of a metal rod ( 3 ) opposite to the dielectric waveguide ( 1 ), the metal rod ( 3 ) being adjacently arranged in parallel with the dielectric waveguide ( 1 ); and a coaxial line ( 5 ) which pierces the metal rod ( 3 ) and connects the dielectric waveguide ( 1 ) with the microstrip line ( 4 ).
