摘要：
We report on the simulated performance of a two-layered Microstrip and Coplanar Waveguide (CPW) band-pass filters by using one layer simulation method. The two layer is composed of Ag(Ta0.5Nb0.5)O-3 (ATN) thick film and alumina substrate. The ATN thick film of about 7m in thickness is prepared by screen printing method on an alumina substrate of about 635m in thickness at a sintered temperature and time of 1150 degrees C and 2 hrs, respectively. Au conductor of about 2m in thickness is deposited by sputtering method. The 2-pole band-pass filters are designed for a center frequency of 5.88GHz, and 5.76GHz with 7.8% and 8.6% bandwidth, respectively. Both ATN-based filters offer a similar selectivity as well as a loss parameter compared to that of two-layer simulation.
