Abstract :
The design and performance of 180 GHz substrate integrated waveguide filters is presented. It is shown that photoimageable thick film technology can achieve the precise dimensional control needed for design at G-band. TRL calibration standards are fabricated in the substrate integrated waveguide medium itself and excellent results are obtained for the 140-200 GHz frequency range. 0.1 and 0.01dB ripple filters are designed and fabricated, with 8 and 6.2% relative bandwidths. The measured results show excellent agreement with electromagnetic simulations.
