An ultra-wideband (UWB) bandpass filter synthesis and design, using a multiple resonance resonator (MRR), is presented. Mixed-mode coupling is used to introduce a finite transmission zero to increase the filter selectivity. The equivalent circuit of the design is used to find the filtering function using even-odd mode analysis. The synthesis procedure is done on an extracted filtering function in...
In this paper a highly selective ultra-wide band (UWB) bandpass filter is designed using interdigital parallel coupled lines (IDPCL) and multiple resonance resonator (MRR). Interdigital capacitor (IDC) is used to achieve strong coupling between short circuit stubs. Mixed coupling produced by IDC and coupled short circuit stubs introduce a finite transmission zero. This transmission zero will increase...
In this paper a high selective compact ultrawide band (UWB) bandpass filter has been designed using a novel multiple resonances resonator (MRR). Equivalent circuit has been extracted for the proposed single order MRR where the filtering function was derived, showing the feasibility of a maximum of six transmission poles in the passband. Finite frequency transmission zero was introduced by having a...
