Loss reduction methods using porous silicon for filter design on lossy substrates are investigated. The results show that the underlying bulk silicon properties play an important role in the resulting performance of the filter. Reduction in the thickness of the lossy underlying bulk silicon leads to a 30 % decrease in the insertion loss in the passband (at 10 GHz) and as 35 % improvement in the stopband performance (35 GHz).
