The proposed design consists of two 14-GHz and 28-GHz band pass filters (BPFs). Each BPF consists of elliptical OLRRs that couple two microstrip lines. The geometrical parameters of both BPFs can easily adjust the passband and stopband frequencies to the desired frequencies. The proposed elliptical-shaped OLRRs show good broadband characteristics. The longer OLRR is responsible for achieving passband at the lower resonant frequency of 14-GHz while the shorter OLRR is used to generate a 28-GHz resonant frequency. The proposed diplexer has good return losses and insertion losses at the two resonant frequencies of 14-GHz and 28-GHz.","PeriodicalId":166697,"journal":{"name":"Proceedings of 2014 Mediterranean Microwave Symposium (MMS2014)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123521593","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 use of indirect microwave holography enables the complex field scattered from the object under imaging to be recovered from intensity-only scalar microwave measurements and therefore removes the requirement of using expensive vector measurement equipment. This significantly reduces the cost of the imaging system and simplifies the hardware implementation. Following the successful implementation of indirect holography method for shape and position reconstruction, we have explored an algorithm which combines indirect holography method and CSI method to solve the phaseless data reconstruction problem. Results presented here indicate that the material properties of composite dielectric objects can be accurately reconstructed using scalar measurements from indirect holography.","PeriodicalId":166697,"journal":{"name":"Proceedings of 2014 Mediterranean Microwave Symposium (MMS2014)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127690078","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}

Furthermore, the measured read range was found to be 0.56 m at 915 MHz.
