Dielectric waveguide corner and power divider with a metallic reflector

The right-angle corner and T- and Y-junction-type power dividers with the metallic reflector are experimentally investigated which are useful for dielectric waveguide millimeter-wave integrated circuits. These devices have been fabricated from the rectangular dielectric image line and have been tested in the 20-26 GHz range. The tested corner exhibits the bending losses 1.0-1.75 dB for single-mode operation and 0.23-0.7 dB for multimode operation. The tested Y-junction-type power divider exhibits the power division of about 4.4 dB and the isolation is above 20 dB. The metallic reflector can be applied to other passive components.
