Matched load for WR03 waveguides

[摘要] In this research, a design and simulation of a waveguide termination for WR03 band, using SU8 based micromachined waveguides is reported. To achieve low level reflection for the termination, two basic ideas are considered. Firstly, an open-ended waveguide port inside the lossy material of SU8 has been investigated. Secondly, thin film conductor layers (silver and platinum) are considered for waveguide walls. Additionally, for the improvement of the final result, different kinds of tapering of the SU8 open-ended waveguide have been analysed. Horn shaping of the waveguide structure in combination with tapering of SU8 has also been evaluated. The best structure was WR03 Platinum termination with height tapering with a predicted return loss of better than -30 dB over the WR03 band.
