A dielectric perturber is attached to the end of a PET cantilever beam and suspended above the designed DBBPF. By applying a DC bias voltage, the PET actuator vertically lifts up or pulls down the attached dielectric perturber. The height of the dielectric perturber from the DBBPF determines the effective dielectric constant, causing a variation of the filter's center frequency. The proposed DBBPF provides concurrent dual passband tuning operation for multiband wireless systems.","PeriodicalId":334390,"journal":{"name":"2017 USNC-URSI Radio Science Meeting (Joint with AP-S Symposium)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122152241","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}

Using COMSOL Multi-physics, we investigate the transmission characteristics of such structures with variation of the physical parameters gap width, dielectric constant, gap separation, and incident angle.

This question was given a positive answer in a recent internship after which a prototype for (de-)compression was tested in two field experiments. Large volumes of weather were shown to be reduced to less than a percent of the original datasets but this came with the price of information loss. In this study a method for lossy compression of weather data is described by representing the data as a sparse and adaptive subset. Adaptive sampling is then solving an optimization problem for the minimal loss of information for applications in radar propagation modeling.","PeriodicalId":334390,"journal":{"name":"2017 USNC-URSI Radio Science Meeting (Joint with AP-S Symposium)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122158322","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}

Micromixer-based gain-enhanced technique, i.e. inductive series-peaking gain-enhanced single-in differential-out (SIDO) class-AB RF GM stage, is used to increase the output impedance and suppress the feedback capacitance Cgd of RF GM stage. Hence, conversion gain (CG), noise figure (NF) and LO-RF isolation of the mixer can be enhanced. The mixer consumes 7.2 mW and achieves excellent RF-port input reflection coefficient of −10∼ −14.4 dB for frequencies of 81.4∼110 GHz. The corresponding −10 dB input matching bandwidth is greater than 28.6 GHz. In addition, for frequencies of 90∼96 GHz, the mixer achieves CG of 10.5∼12 dB (the corresponding 3-dB CG bandwidth is 22 GHz) and LO-RF isolation of 40.2∼46.2 dB, one of the best CG and LO-RF isolation results ever reported for a down-conversion mixer with operation frequency around 94 GHz. Furthermore, the mixer achieves an input third-order intercept point (IIP3) of 1 dBm at 94 GHz. These results demonstrate the proposed down-conversion mixer architecture is very promising for 94 GHz image radar sensors.","PeriodicalId":334390,"journal":{"name":"2017 USNC-URSI Radio Science Meeting (Joint with AP-S Symposium)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125728504","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}
