Abstract
Low-loss dielectric waveguides are promising to be used instead of metal on es, but problems in transitions have to be overcome, Simple and effective s tructure made of monocrystalline sapphire waveguide has been designed. Expe rimental results at 75-110 GHz indicate good matching with metal waveguide (VSWR (less than or equal to1.13) and low insertion loss (0.05-0.35 dB for 47 mm dielectric section).
