Abstract
We have discussed the three types of millimeter waveguides for reducing the transmission loss. The diffusion-bonding hollow-waveguide array of copper achieves 60% antenna efficiency for 31.4 dBi gain at 93.7 GHz. The hollow waveguide of laser-curing resin with copper electroplating with 25 mm length achieves -0.1 dB transmission at 94GHz. The dielectric half-filled parallel plate waveguide is expected to reduce the transmission loss by about 40% in 60GHz band.
