A conventional coupler loaded with half-wavelength short-ended stubs is adopted to realize the dual-band operations. Moreover, the frequency is tunable by changing the characteristic impedance of the transmission line. For practical verification, a branch line coupler ($varepsilon_{mathrm{r}}=2.65, h=0.5 text{mm}$) operation at 0.9/1.8GHz is constructed in microstrip technology and tested. The measured results are in good agreement with the simulated ones.","PeriodicalId":247909,"journal":{"name":"2019 International Applied Computational Electromagnetics Society Symposium - China (ACES)","volume":"458 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123047607","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 U-slot microstrip patch antenna is designed based on an empirical design technique and then analyzed using the theory of characteristic modes (TCM). The radiation modes and scattering modes of the U-slot patch antenna are distinguished by examining the CM indicators, including modal significances, modal currents, and modal fields. According to the designated frequency band and angular range for RCS reduction, a specific scattering mode is selected and loaded with lumped elements. Values of the lumped elements can be calculated theoretically in this method and a maximum RCS reduction of 20 dB is obtained.","PeriodicalId":247909,"journal":{"name":"2019 International Applied Computational Electromagnetics Society Symposium - China (ACES)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117052355","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 input sample of the model is the size parameter of the antenna, and the output sample is the difference of the electromagnetic simulation calculation result and the prior knowledge, thus establishing the Gaussian process model. This modeling method is used to model the resonant frequency of the coplanar waveguide feed dual-frequency microstrip antenna, and the error result is ideal.
