Abstract

An improved SIFW structure is proposed for the first time in this paper. Base on the new structure, two novel millimeter-wave SIFW BPFs have been analyzed and designed in this paper. Through the cross-coupling, the filters could provide TZs on lower and higher stopband which greatly enhance the side-band rejection. LTCC technology is also implemented to realize further compact size of this filter. Moreover, the length of the filter is nearly half of the unfolded counterpart, which has important significance for system´s miniaturization.
