Return loss coefficient and radiation pattern of this antenna are computed in free space as well as in the presence of head. The specific absorption rate (SAR) of the planar antenna is calculated and compared with that of the monopole antenna. To examine the performance of this antenna, a prototype was designed, fabricated and measured; the simulation analysis was performed using the HFSS software, good agreement with the simulation providing validation of the design procedure.","PeriodicalId":300247,"journal":{"name":"2009 Mediterrannean Microwave Symposium (MMS)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123995917","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}

In addition, to get a wider bandwidth filters, tightly coupled lines are required, which are difficult to fabricate. On the other side a compact bandpass filter means the lowest number of sections with small size. This paper presents a technique to design a compact microstrip X-band bandpass filter using two sections and a stub to have a compact size, good sharpness on the sides, and small loss. Experimental prototype filters have been designed and measurement results show improved performance compared with the other regular cascaded coupled line bandpass filters.","PeriodicalId":300247,"journal":{"name":"2009 Mediterrannean Microwave Symposium (MMS)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132982635","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}

Computation of the dispersion diagram of both metasurfaces highlights the possibility to obtain forward and backward waves, respectively. The backward waves can be achieved only at the quasi-static resonance in case of stacked CSRRs metasurfaces and provided the longitudinal lattice is small enough. The experimental results for both structures show a good agreement with the computed ones. The physics underlying the left-handed behavior is found to rely on electroinductive waves, playing the interplate capacitive coupling the major role to explain the phenomenon.","PeriodicalId":300247,"journal":{"name":"2009 Mediterrannean Microwave Symposium (MMS)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132817069","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}

Several advanced UWB filters are demonstrated with electromagnetic (EM) simulated and experimental results. The filters are based on a circuit model for an optimum distributed highpass filter consisting of short-circuited stubs separated by non-redundant connecting lines. It is shown that a cross-coupling between non-adjacent resonators or between the input and output (I/O) feed lines can be implemented to generate new transmission zeros which improve the performance of the stub filters. It is also demonstrated that the uniform connecting lines of the stub filter can be replaced by stepped-impedance lines to suppress the spurious harmonic passbands. In addition, stepped-impedance resonators (SIRs) are implemented to generate a narrow notched band inside the UWB passband to avoid interference with existing radio signals.","PeriodicalId":300247,"journal":{"name":"2009 Mediterrannean Microwave Symposium (MMS)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114771957","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}
