The developed duplexer has an isolation higher than 70 dB, which enables cellular transceiver RFICs to meet stringent linearity requirements without inter-stage SAW filters and sophisticated linearization techniques. The authors call such a highly isolated duplexer “super-isolation duplexer”. The progress of transceivers RFICs is also reviewed and the best solution for a SAW-less RF front end is considered.","PeriodicalId":232128,"journal":{"name":"2009 European Microwave Conference (EuMC)","volume":"243 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124677406","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}

Relative permittivity and loss tangent are computed from S-parameter measurements and analytical equations. The analytical computation is either direct by using equations derived from Bahl formulas, or iterative by using Jensen-Hammerstad formulas coupled with the efficient secant algorithm. Thin film microstrip transmission lines have been fabricated for the extraction of dielectric electrical properties of SU-8 resin. A relative dielectric constant of 2.85 and a loss tangent of 0.04 were determined. These values are used in an EM simulator for the design of an SU-8 based High-Q inductor implemented on a low resistivity silicon substrate. The good agreement between measurements and simulations validates the characterization procedure and confirms the relevance of SU8 for applications up to 15 GHz.","PeriodicalId":232128,"journal":{"name":"2009 European Microwave Conference (EuMC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126908387","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}

In this framework, the main challenges are the detection of targets located on the other side of a wall and the monitoring of their motion. To pursue these aims, we propose an imaging strategy based on the Linear Sampling Method (LSM), a computationally effective tool to determine the targets' morphology from multiview, multistatic and monochromatic data. In particular, by relying on the physical interpretation of LSM, we give its formulation for TWI and propose its use for motion tracking purposes by means of a simple post-processing strategy. A numerical example is given to assess the performances of the approach.","PeriodicalId":232128,"journal":{"name":"2009 European Microwave Conference (EuMC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116337038","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}

For many practical array and multiport antenna designs it is essential to examine the farfield for a general port excitation or termination scenario. Some examples are phased array designs, problems related to mutual coupling and scan blindness, tuning of parasitic elements, MIMO antennas and correlation. The proposed method fully characterizes the nearfield and the farfield of the antenna, so to compute farfield patterns by means of superposition for any voltage/current state at the port terminals. A recently published low-cost patch antenna phased array with analog beam steering by another group was found very suitable to demonstrate the proposed method.","PeriodicalId":232128,"journal":{"name":"2009 European Microwave Conference (EuMC)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121449781","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 novel transponder consists of a linearly polarized UWB circular monopole antenna coupled to an orthogonally polarized novel dual multi-resonant dipole antenna. The dual multi-resonant loop antenna has a gain of over 5 dB for all resonances and creates a frequency signature in the orthogonal polarization of the interrogation signal.
