Non Radiative Dielectric Waveguide Having A Portion For Line Converstion Between Different Types Of Non Radiative Dielectric Waveguides

摘要

In a millimeter wave module that mixes a normal NRD guide with a hyper NRD guide, it is heterogeneous that it has excellent transduction properties at the interface between the NRD guides and the transducer structure for non-radiative dielectric waveguides. In the first part it is the dielectric strip, in the hyper NRD guide it is from the dielectric strip it width, in the normal NRD guide part it is changed to the dielectric strip it width. In a hyper NRD guide it is the same depth as the grooves and the grooves are the second it is installed extending as far as the transformer. Thirdly, in the conversion part, the electromagnetic waves propagate perpendicularly to the propagation direction, and the conductive plates are parallel to the plane of these grooves. According to this structure, the guide conversion can be achieved with a predetermined low frequency in the frequency band.
