A stepped impedance resonator with a shorting stub and a uniform impedance resonator with an open stub are applied in the design. Several techniques that can generate transmission zeros are combined to improve the frequency selectivity. The resonators and the proposed filter are characterized by full-wave simulations. To validate the design strategies, The tri-band BPF centered at 2.4 GHz, 5.2 GHz and 5.8 GHz was developed. Both simulations and measurements were carried out to demonstrate the effectiveness of the design. Good agreements are achieved.","PeriodicalId":326539,"journal":{"name":"2018 11th UK-Europe-China Workshop on Millimeter Waves and Terahertz Technologies (UCMMT)","volume":"153 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126926553","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}

Tracking all visible satellites simultaneously costs huge computation sources. In this paper, we propose a novel satellite selection method based on genetic algorithm (SSMGA), which could select exact satellites from multi-constellation with optimized Geometric Dilution of Precision (GDOP) values. After several experiments, the key parameters of genetic algorithm have been determined by selection, crossover and mutation. In the meantime, the local optimal solutions of satellite selection is solved. SSMGA has been evaluated under multi-constellation and variable navigation satellites combination. The simulation results between SSMGA and traditional optimal satellite selection algorithm (TOSSA) indicate that SSMGA has a significant improvement on the computational complexity with the same accuracy according to GDOP. The time consumption of SSMGA dramatically decreases 70% compared with TOSSA in three satellite selection configurations among four constellation: GPS, BDS, Galileo and GLONASS.","PeriodicalId":326539,"journal":{"name":"2018 11th UK-Europe-China Workshop on Millimeter Waves and Terahertz Technologies (UCMMT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122324265","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 inverse problem of obtaining permittivity is solved by artificial neural network.
