Ltcc Ultra Wide Band Filter
نویسندگان
چکیده
This article presents the analysis of ultra wide band (UWB) filter designed using a symmetrical three parallel coupled line resonator in low temperature co-fired ceramic (LTCC) medium. The ground plane with an aperture incorporated in it improves the coupling. Based on circuit models, the designed UWB filter has been analyzed, and the results have been confirmed by experiments. The filter has been realized with Dupont LTCC tape DuPont 951 (that has dielectric constant of 7.8). Maximum insertion loss of the experimental filter is 1.5 dB. The group variation over the pass band of the filter is within 0.2 ns. Dimensions of the experimental LTCC filter are 20 10 0.72 mm. VC 2011 Wiley Periodicals, Inc.

متن کاملA Novel Compact Dual Notch Band Filter Based on Metamaterial Concept
Using composite right-left handed (CRLH) transmission line concept, a novel miniaturized dual notch band filter (DNBF) is proposed. The suggested DNBF consists of an interdigital transmission line (ITL), split ring resonators (SRRs) and complementary split ring resonators (CSRRs). Since the resonance frequency of the SRRs and CSRRs are quite independent of each other, the dual notch bands of th...

A compact and sharp-rejection ultra-wideband (UWB) microstrip band-pass filter (BPF) is developed using of left handed metamaterials realized by complementary split ring resonator (CSRR). Moreover, proposed structure consists of two doublets parallel coupling gaps at each side of a microstrip ring. In comparison with some other filters, this structure shows a significantly wider passband due to...
