ABSTRACT:
In a millimeter wave module or the like having both a normal NRD guide and a hyper NRD guide, a conversion portion structure for non, radiative dielectric waveguides of different types has excellent conversion characteristics at the connection between the two types of NRD guides. In a first conversion portion, the width of a dielectric strip is changed from the width of a dielectric strip in the hyper NRD guide portion to the width of a dielectric strip in the normal NRD guide portion, grooves of approximately the same depth as grooves in the hyper NRD guide are provided extending as far as the second conversion portion, and in a third conversion portion, the width of these grooves widens perpendicular to the propagation direction of electromagnetic waves and parallel to the face of conductive plates. According to this structure, guide conversion can be achieved with low radiation in a predetermined frequency band.
