A wideband NRD guide and rectangular waveguide H-plane transition is proposed to transfer millimeter waves from a dielectric strip to the outer conductor surface of NRD guide through a short length of waveguide made through the conductor plate. As a result, it has a bandwidth about 6.7 GHz of |S11| -15 dB and a low transition loss about 0.35 dB at 60 GHz band.
