摘要：
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 characteristics, a transition to another waveguide is needed. In this paper, a transition structure from a rectangular waveguide to an image NRD is proposed and its operating principle is explained. Also, by means of numerical calculations based on the effective dielectric constant (EDC) method, a transition intended for use in the R band (30 GHz) is designed. Further, the designed transition is measured and the effectiveness of the proposed transition is demonstrated. (C) 2001 Scripta Technica.
