Abstract
A method of manufacturing a waveguide includes forming two waveguide units, each waveguide unit having a channel defined by a bottom wall and two side walls generally transverse to the bottom wall, flanges extending from the side walls, outside the groove, transverse to the side walls and generally parallel to the bottom wall, the flanges including though holes; joining the two waveguide units to each other so that the flanges of a first of the waveguide units abut the flanges of a second of the waveguide units, with the grooves forming a channel for guiding waves; and, by insert molding, forming a thermoplastic resin cover that fills the through holes in the flanges and covers both of the first and second waveguide units, at least partially.
