It is based on the higher order mode cavity and buried slotline. The wideband transition of SIW TE20 mode is employed to realize the out-of-phase divider while the microstrip-to-slotline transition is used to realize the in-phase divider. The slot is etched on the top of the higher order mode cavity. The ground metal defects are buried inside the multilayer substrate, and thus, in practical applications, additional bolster is not required for the defected ground slot. It is convenient for the proposed magic-T to be integrated with other circuits.","PeriodicalId":269888,"journal":{"name":"2015 Asia-Pacific Microwave Conference (APMC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115006418","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}

Three different modules, namely RF-MEMS switch, through-silicon-via (TSV) and microfluidics, are added to IHP's BiCMOS technologies. The first extension module of RF-MEMS switch adds a high-performance mechanical switch, providing unique features such as low-loss switching or high-Q tuning at mm-wave frequencies. The TSV module, which adds deep vias through the substrate (silicon), provides low-ohmic vias through the front side to back side of the silicon wafer. Using this module, the back side of the silicon chip can be used as the RF-ground. Furthermore, such vias through the substrate enables the 3D integrated packages. The last extension module, microfluidics, adds the micro-channels inside the BiCMOS chip. Such micro-channels are very promising for bio-sensing applications for THz detection. The brief technological information of each module and some design examples are also provided in this paper.","PeriodicalId":269888,"journal":{"name":"2015 Asia-Pacific Microwave Conference (APMC)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114998337","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 proposed one is designed with planar active dipoles and parasitic element arrays from an Yagi-Uda design methodology. Four orthogonal arrays are configured of two active elements and eight parasitic elements, which is implemented with two bi-directional arrays. Each array has an active element, two reflector elements, and two director elements. The proposed architecture has been implemented on a planar substrate, and controlled with switched reactance for each parasitic element.
