A novel class of miniaturized multi-mode wideband bandpass filters (BPFs) is introduced this paper, includes four multiple-mode filters. Two of them are realized using metal cavity and two of them are realized using substrate integrated waveguide (SIW). These filters have significant advantages in size reduction which can reduce 2.5-4 times compared with traditional single-mode cavity filter. The...
Two SIW bandpass filters (BPFs) are presented using rectangular cavities and loaded posts for 5.8GHz WLAN system using rectangular cavity and loaded posts. Except that both of them use two rectangular cavities to create a passband, they are different in setting the feed-line locations. In design, two loaded posts are introduced as inductive coupling elements to restrain the fundamental resonant mode...
A class of microstrip triple-mode bandpass filters (BPFs) using a patch-loaded cross resonator are modeled, designed and tested in this paper. First, a symmetrical equivalent LC network is developed for a symmetrical patch structure. The values of all the inductors and the capacitors are extracted by applying the even-odd mode analysis. Then, three 1-port networks are developed to analyze the resonant...
A class of triple-mode ultra-wideband (UWB) microstrip-line bandpass filters with improved upper-stopband performance and miniaturized size is proposed. Firstly, a mode graph of the initial triple-mode resonator is studied to choose its proper dimensions, aiming at allocating its first three resonant modes located within 3.1-10.6 GHz and its transmission zeros near its 5th-7th resonant modes. As a...
An ultra-wideband (UWB) microstrip bandpass filter with improved upper-stopband and miniaturized size is presented. A modified multiple-mode resonator is formed by transversely attaching three pairs of non-uniform and folded stubs. Its configuration is then investigated, aiming to allocate the first three resonant frequencies within 3.1-10.6 GHz band while suppressing spurious harmonics at the upper-stopband...
