The metamaterial TL proposed is constructed by a series capacitive gap between two metal patches combined with a complementary single Archimedean spiral resonator (CSASR) etched in the ground plane. The equivalent circuit model is applied to analyze the proposed antenna. The dispersion curve is calculated and analyzed, indicating that the TL has two balanced zeroth-order resonant (ZOR) frequencies on which the antenna operates. The particularity is that the proposed TL performs zero refraction (ZR) characteristic in the working bands. For verification, an antenna sample is fabricated and measured. Numerical and experimental results agree well with each other. The two operating bands are respectively 420 and 440 MHz lower than those of the same sized antenna with a traditional complementary split ring resonator (CSRR).","PeriodicalId":438795,"journal":{"name":"2016 IEEE International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130504937","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The basic UWB BPF is realized by feeding a modified multiple-mode resonator (MMR) properly with two aperture-backed interdigital coupled lines. The modified MMR can create five modes in band and two transmission zeros near the lower and upper cutoff frequencies, improving passband selectivity greatly. Then, triple notched bands, together with another transmission zero in the upper stopband, are generated by implementing a coupled quadruple -mode resonator which provides a high degree of adjusting freedom. To validate the design theory, a microstrip UWB BPF with three notched bands centered at 3.6, 5.8 and 8.0 GHz, respectively, is designed and fabricated. The simulated and measured results are in good agreement and show good in-band filtering performance and sharp selectivity.","PeriodicalId":438795,"journal":{"name":"2016 IEEE International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121344591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
