The approach profits from the decomposition of the incident-field vector in field components directed along the diagonal-axis, decoupling the problem into two different, individual and independent subproblems. This issue reduces considerably the complexity of the problem, and allows for a better understanding of the physical insight of the structures. Practical examples of wideband rotators/circular polarizers based on very simple metasurface-cells are implemented with the aim of supporting the theoretical conclusions. Experimental prototypes have suc-cessfully been manufactured and will soon be tested.","PeriodicalId":228461,"journal":{"name":"2022 16th European Conference on Antennas and Propagation (EuCAP)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117169815","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 total harmonic transponder conversion loss is 6.2 dB for an excitation power of -25 dBm at the antenna-diode interface, outperforming state-of-the art solutions. The measured reading distances are 9.0 m and 8.8 m for $mathbf{EIRP}=20mathbf{dBm}$ when the transponder is placed in free space and on the human body, respectively.

Particularly, the use of ultra wideband (UWB) Radar, Electronic Warfare devices or wide band telecommunication systems increases the difficulty to share the allowed frequency band on a platform. Then, the introduction of a narrow forbidden band in these UWB structures is a challenge today. This narrow band can be used for localization, voice, internet, communications using for example another antenna located nearby on the platform, but also inside the UWB antenna itself building a Multifunction Antenna. Agile Radiating Matrix Antennas (ARMA) (Fig1) built with wide band pixels are a good candidate to perform this multi-functionality as shown in this paper.","PeriodicalId":228461,"journal":{"name":"2022 16th European Conference on Antennas and Propagation (EuCAP)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122084219","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 current method to compute the gain, for a given element radiation efficiency, is based on the array factor (AF) theory. This work is intended to show that an equivalent formulation can be done using the Spherical Wave Expansion (SWE). Besides the interest in validating the theory, the main objective is a better understanding of the radiation and attenuation phenomena that occur in compact and superdirective arrays. The limits in their practical implementations are imposed by the high sensitivity of the system. The SWE theory provides more information in the expression of the radiated field, thus unfolding the possibility to address the problem with lower sensitive solutions.","PeriodicalId":228461,"journal":{"name":"2022 16th European Conference on Antennas and Propagation (EuCAP)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122177461","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}

They are particularly suitable for carrying out surveys in areas where manned operation is too dangerous or too expensive, examples being deep sea environments or naval mine clearing operations. However, to make full use of their capabilities, a communication link between AUV and its host platform is necessary. This paper proposes a design for an ultra high frequency (UHF) wideband antenna that can be mounted on mid-sized AUVs. The antenna covers the entire naval UHF frequency band from 225MHz to 400MHz with a reflection coefficient lower than −10dB and an omni-directional radiation pattern. Water effects are taken into account in both, simulations and measurements indicating a stable antenna performance.","PeriodicalId":228461,"journal":{"name":"2022 16th European Conference on Antennas and Propagation (EuCAP)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124006816","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}

GRIN lenses, whose refractive index profiles are spatially-varying, have been shown to improve the gain of antenna systems while in more compact forms. However, optimization of the GRIN lens profiles is difficult because the lenses can be many wavelengths wide, and the simulations slow to compute. Furthermore, the large number of design variables makes solving the GRIN lens profile a challenging problem. However, these problems can be remedied using adjoint sensitivities to compute the gradient for every design variable in only two simulations. Then local optimization approaches can follow these gradients to rapidly converge to a good candidate solution. To demonstrate the efficacy of the approach, a GRIN lens design was optimized to have the same measured broadside gain as a 20 dB standard gain horn.","PeriodicalId":228461,"journal":{"name":"2022 16th European Conference on Antennas and Propagation (EuCAP)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125891411","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}
