ABSTRACT MEMS based mechanical resonators and filters have shown promising characteristics in achieving high Q values and good stability. This paper introduces a novel V-shape coupling element that is used to mechanically couple two clamped-clamped MEMS In order to design filters effectively, it is necessary to be able to predict frequency characteristics of a certain kind of filter structure suitably fast. Considering ceramic filters, instead of 3-D field analysis program, a circuit simulator program is often a good choice for a
