Two critical factors contributing to the bi-static measurement error were discussed: (1) mutual coupling and (2) scattering effect. A conventional horn antenna with a customized 3D-printed GRIN lens was proposed to address those critical issues. The horn antenna with 3D-printed GRIN lens features narrow 3-dB beam width to minimize the scattering effect. The proposed compact 3D-printed bi-static measurement setup shows robust measurement data with low noise.","PeriodicalId":383636,"journal":{"name":"2023 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (USNC-URSI)","volume":"289 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133068725","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 antenna has a monopole structure with two triangles and a few parallel slots cut at the bottom corners and top edge of the radiation patch, respectively, to achieve an optimized ultra-wide bandwidth and a smaller antenna size. The simulated and measured results show that the antenna prototype can realize a bandwidth of 93% from 0.9–3.0 GHz with a realized gain of 3.32 dBi. Furthermore, in order to verify the performance, we investigate the feasibility of classifying brain strokes between an intracranial haemorrhage stroke and an ischemic stroke with this antenna. The S parameter of the antenna varies significantly with the stroke types introduced (i.e., different dielectric constants), which demonstrates the applicability of the antenna for such use scenarios in MMI.","PeriodicalId":383636,"journal":{"name":"2023 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (USNC-URSI)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133502283","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 decoupler consists of a single row of 15 vias, and a copper plate carefully inserted into a high-permittivity superstrate between the two-element MIMO antenna. The vias help to mitigate the surface coupled waves in the antenna substrate, while the copper plate and the high-permittivity superstrate help to alter the space permittivity, disturb the space coupling, and increase the isolation. This combination improved the proposed antenna's isolation by a maximum of 31 dB over the 52–64 GHz bandwidth (14.3%) in the H-Plane, with a very close edge-to-edge spacing of 0.62 mm (0.12λ), where λ is the free-space wavelength at the center frequency of 60 GHz.

For demonstration, the proposed design is fabricated and measured. The dual-band prototype features stable radiation patterns with HPBW $65pm 5^circ$ and wideband matching >10dB in the entire frequency bands of interest.

The discretization of the nonlinear relation between the surface current density and the electric field is approximated such that the final system of equations to be solved are linear. It is applied to solve scattering of a Gaussian plane wave by a sphere possessing a strongly nonlinear conductivity relation. This solver is developed to specifically model the effects due to the region of negative differential conductivity in the conductivity relation, which is expected in graphene superlattice structures. Numerical results demonstrate the stability and convergence of the method and the ability to enforce the constitutive relation within controllable error bounds.","PeriodicalId":383636,"journal":{"name":"2023 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (USNC-URSI)","volume":"197 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115716665","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}

As many surveillance and radio-frequency positioning systems relay on measuring DoAs, improving the DoA accuracy is of great importance. However, due to the limited array dimension, the DoA accuracy of the arrays composed of identical elements is fundamentally difficult to improve. Besides, given the limited number of elements, arbitrarily increasing the array dimension can cause ambiguity. To alleviate these issues, we employ antennas with diverse shapes of radiation patterns to improve the DoA estimation accuracy. We compared the DoA estimation accuracy of a uniform linear array of three rectangular patch antennas and that of the same array of two rectangular patch antennas and one low-profile antenna with a monopole-like radiation pattern. Theoretical and Monte Carlo simulation results demonstrate that the DoA estimation error of the array composed of diverse antennas can reduce by up to 30% over a wide field of view.","PeriodicalId":383636,"journal":{"name":"2023 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (USNC-URSI)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124187901","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}
