A beam pattern design requires tuning the phase shifter value of the antenna, and it takes expensive computational cost to find the desired beam pattern. In this paper, we propose a method to obtain the phase shifter value corresponding to the desired beam pattern through a DNN (Deep neural network) based model to reduce the iterative computational cost. The DNN model is trained based on the extracted data through the simulation tool, and the validation is performed by comparing a simulated beam pattern using estimated phase shifter values through trained DNN model with desired beam pattern.","PeriodicalId":137840,"journal":{"name":"2022 International Symposium on Antennas and Propagation (ISAP)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123365106","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 fabricated prototype not only possesses broad measured 1-dB and 3-dB gain bandwidths of 24.5% (10.75-13.75 GHz) and 33.3% (10-14 GHz), respectively, but also yields a wide 1.5-dB axial ratio (AR) bandwidth of 37.4% (9.25-13.5 GHz), which achieves high-purity circular polarization.

Simulating such environments typically requires large-scale models. The Finite-Difference Time-Domain (FDTD) method is a widely used numerical electromagnetic simulation method. However, this method is typically not suited for simulating large-scale models. The Multiple-Region (MR) FDTD method addresses some down-sides of the FDTD method. However, its calculation speed can still be slow.

The sensor consists of a stretchable inductor with a symmetric serpentine structure and a circular interdigitated capacitor to form an resistor-capacitorinductor (RCL) resonant circuit. The alcohol concentration change modifies the environmental dielectric constant of the capacitor and consequently the resonant frequency of the RCL circuit, which can be measured wirelessly with a primary coil. Both high-frequency structure simulator (HFSS) simulations and experiments verify the dependence of the resonant frequency on the alcohol concentration in the alcohol/water mixture. Using pigskin to simulate human skin validate the good sensitivity of the device and its feasibility in continuous monitoring of alcohol concentration in biofluids.
