Abstract
The image NRD guide as a modification of the NRD guide is expected to find applications at millimeter wave frequencies. In order to construct circuits and antennas containing image NRD guides and to evaluate their characteris tics, a transition to another waveguide is needed. In this paper, a transit ion structure from a rectangular waveguide to an image NRD is proposed and its operating principle is explained. Also, by means of numerical calculati ons based on the effective dielectric constant (EDC) method, a transition i ntended for use in the R band (30 GHz) is designed. Further, the designed t ransition is measured and the effectiveness of the proposed transition is d emonstrated. (C) 2001 Scripta Technica.
