The average power handling capability (APHC) which refers to self-heating is considered. The ohmic and dielectric losses expressions are used to predict the APHC as a function of the geometrical parameters and used material. In fact, small dimensions and the increased losses at millimeter-waves dramatically reduce the power handling capability. Moreover, the additional effect of the surface roughness doubles the conductor loss at millimeter-wave frequencies. The proper material and dimensions selection for SIW, which could increase its APHC are discussed. In addition, guidelines for investigating the oversized version of SIW are also presented. To investigating the oversized version of SIW are also presented. To validate the simulations, a set of transmission lines (microstrip, The good agreement of measured losses with the calculated validates this study.","PeriodicalId":226787,"journal":{"name":"2021 IEEE MTT-S International Microwave and RF Conference (IMARC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121688817","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 key challenges for the imaging of the buried objects are the antenna cross talk and the presence of ground bounce. The GPR imaging is more difficult in complex ground scenario which is unpredictable. For imaging of subsurface objects, an efficient and reliable signal processing scheme is essential. Here we have implemented a complete imaging scheme for buried object detection. The important steps such as clutter removal, velocity analysis, migration techniques are implemented for imaging buried object. The effectiveness of the scheme is verified by processing synthetic data as well as laboratory measurements. The proposed approach can be effective for buried object detection.","PeriodicalId":226787,"journal":{"name":"2021 IEEE MTT-S International Microwave and RF Conference (IMARC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127079545","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}

Baluns are important components for 300-GHz-band circuits, and they are required to have wide bandwidth, low loss and small size. Passive baluns such as a rat-race balun and Marchand balun have good performance, and the Marchand balun can be smaller than a rat-race balun because the Marchand balun uses coupling lines. However, the size of the Marchand balun is determined by the ground shields in the terahertz band, and the optimum structure has not been clarified. In this work, we realize small Marchand balun with wide bandwidth and low loss by revealing the optimum distance between the signal lines and the ground shields. The proposed Marchand balun is fabricated using a 0.13 μm SiGe BiCMOS process. The proposed Marchand balun has a center frequency of 275 GHz, a bandwidth of 110 GHz, an insertion loss of 1.4 dB and an area of 0.008 mm2. It is shown that the proposed Marchand balun has the lowest loss and the smallest area compared to conventional millimeter-wave and 300-GHz-band baluns.","PeriodicalId":226787,"journal":{"name":"2021 IEEE MTT-S International Microwave and RF Conference (IMARC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113996189","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}

Stepping in CPW (Coplanar Waveguide) topology is carried out to ensure $50Omega$ matching at excitation port and to provide adequate field localization over the sensing region. The central region of the stepped coplanar line is used as a sensing area where MUT (Material Under Test) can be placed for dielectric constant and defect detection. The Efield plots of conventional and proposed topologies are analyzed to show the enhanced field confinement. The performed numerical analysis shows that the proposed sensor produces an improved phase shift in transmission parameter (5°) than that of the conventional CPW (2°) counterpart for identical change in the dielectric constant. Finally, a numerical analysis is performed to appreciate the defect detection attribute of the designed sensor corresponding to the two samples with different profile of air void (defect pattern). It is found that the sensor may produce significant phase shifts corresponding to each sample, including defect-less samples, due to its improved phase sensitivity.","PeriodicalId":226787,"journal":{"name":"2021 IEEE MTT-S International Microwave and RF Conference (IMARC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126500567","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}
