This paper proposes a regression-based ANN model to predict the complex permittivity of polar liquids for a range of temperature and frequency using the Debye parameters -static permittivity and high frequency permittivity. The model was built based on the dataset obtained from National Physical Laboratory report MAT 23. The proposed model predicts the complex permittivity without the prior knowledge about the best fit Debye equation and related calculations. The model development was initiated with data preprocessing technique followed by parametric tuning and performance evaluation. This model offers a result of low mean square error and it was validated by comparing the actual data with the predicted data.","PeriodicalId":325720,"journal":{"name":"2020 International Symposium on Antennas & Propagation (APSYM)","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131565285","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 design is made of a circular ring resonator loaded with four lumped resistors and a circular-split cross dipole, printed on the top of a dielectric substrate terminated with the ground. In the azimuthal plane, the proposed structure is insensitive to different polarization angles of the electric field due to the four-fold symmetry, and it also demonstrates a stable absorptivity up to 45° for both Transverse Electric (TE) and Transverse Magnetic (TM) incidences in the elevation plane. Multiple plasmonic resonances are responsible for the broadband behaviour, and the ohmic losses in lumped elements are the reason for near-unity absorption over the broadband. The response of the proposed equivalent transmission line model is validated with the full-wave analysis up to a reasonable extent. To the best of authors knowledge, this design is angular stable absorbing metasurface operational with limited chip resistors over broadband without compromising the performances, and it is suitable for the applications like Radar Cross Section (RCS) reduction and RF energy harvesting.","PeriodicalId":325720,"journal":{"name":"2020 International Symposium on Antennas & Propagation (APSYM)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126740651","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}

Wireless capsule endoscopy is a modern, non-invasive technique to diagnose the gastrointestinal tract for cancer, Crohn's disease, bleeding, etc. Hence this diagnostic technique has the utmost importance which attracted attention in recent times. To achieve higher data rates and frame rates with higher image resolution, an inner wall dual loop antenna with a u-slotted patch at the UWB band (3.1 GHz to 10.6 GHz) is proposed in this paper. The simulated results show the antenna's excellent performance in terms of return loss with a bandwidth of 7.5 GHz ranging from 3.1 GHz to 10.6 GHz. The antenna is quasi omnidirectional with maximum gains of -36.78 dBi, -38 dBi, -34.36 dBi, and -34.68 dBi at 3 GHz, 5 GHz, 8 GHz, and 10 GHz respectively which is common in antennas for wireless capsule endoscopy because of the highly lossy environment.","PeriodicalId":325720,"journal":{"name":"2020 International Symposium on Antennas & Propagation (APSYM)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125328043","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}
