Title:
導波管マイクロストリップ線路変換器
Document Type and Number:
Japanese Patent JP6778431
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a waveguide microstrip line converter capable of suppressing generation of resonance over a wide range of a millimeter wave band at low cost and easily.SOLUTION: A waveguide microstrip line converter 100 is configured to convert a transmission mode between a waveguide and a printed circuit board. The waveguide microstrip line converter 100 comprises: a printed circuit board 101 including microstrip line parts on both principal surfaces; a first member 102 covering one principal surface 101a of the printed circuit board; and a second member 103 covering another principal surface 101b of the printed circuit board. Each of the first member 102 and the second member 103 includes a recess that is functioned as a waveguide, at the side of the printed circuit board 101 and a bottom wall of the recess of the first member has a step.SELECTED DRAWING: Figure 1
