It generates a wide stop-band with three transmission zeros at the high-side skirt at 3.3GHz, 5.2GHz, 5.7GHz respectively to reject interferential frequencies. The passband insertion loss is less than 2dB. The measured results evidence the feasibility of the proposed design.","PeriodicalId":150727,"journal":{"name":"The 2012 International Workshop on Microwave and Millimeter Wave Circuits and System Technology","volume":"163 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122504012","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}

To analyze the EMI, a UWB signal model was built firstly, along with its four typical UWB channels, under the WiMax interfering signal existence; then, based on the models of the signals and the channels, the UWB transmission performances under the interfering conditions are investigated. Simulated results show that the UWB system can be greatly interfered by the EMI signal; finally, some effective solutions are given. It is pointed out that the existing UWB specifications should be more strictly regulated when the WiMax EMI is considered in our proposed scenario.","PeriodicalId":150727,"journal":{"name":"The 2012 International Workshop on Microwave and Millimeter Wave Circuits and System Technology","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122574336","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}

However, they are inadequate in optimization design. Genetic algorithm (GA) optimizers are robust, stochastic search methods. They are particularly effective to find an approximate global maximum/minimum in a high-dimension, multimodal function domain in a near-optimal manner. Combining EMSS and GA is expected to design and optimize microwave/millimeter wave components effectively such as antennas, filters, couplers, etc., and it is expected to save time and effort of engineers. In this paper, HFSS software, as an example, is combined with GA through VBScript to explicate the method and steps of the combination. Finally, the design and optimization of a compact ortho-mode transducer at Ka band is carried out as an example to demonstrate the validity of the EMSS and GA combination method.","PeriodicalId":150727,"journal":{"name":"The 2012 International Workshop on Microwave and Millimeter Wave Circuits and System Technology","volume":"268 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122918899","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}
