It can fully exploit the data envelope information and temporal correlation to improve the system recognition performance. Electromagnetic (EM) scattering property measurements for electrically large objects are costly and time-consuming, affected by various environmental factors. The high-frequency approximate technique, namely the shooting and bouncing ray method (SBR), is introduced to quickly acquire high resolution one-dimensional range profile (HRRP) of electrically large complex objects. Both the corner reflector and the model car are measured to validate the accuracy of the SBR method. The method is employed to establish HRRP database for various vehicles in traffic scenarios. Deep learning can automatically study data deep features and show outstanding performance in various classification tasks. The residual network (ResNet) and gated recurrent unit (GRU) models are combined to capture and aggregate scattering information of objects. ResNet uses 1-D convolutional kernels and residual blocks to efficiently capture the scattering information within each distance cell while avoiding gradient vanishing or gradient explosion issue. GRU aggregates scattering information along the spatial dimension to construct object feature representations. The combination of them can take advantage of their respective strengths to fully mine the information of HRRPs. Compared with the conventional methods, the features extracted by the proposed model from each class are more concentrated shown in the result of t-distributed stochastic neighbor embedding. The deep model exhibits a superior average recognition rate up to 95.56%, significantly higher than existing methods. It shows robustness to noise, thereby showcasing good potential for practical applications within the Internet of Vehicles (IoVs).","PeriodicalId":34267,"journal":{"name":"IEEE Open Journal of Antennas and Propagation","volume":"6 2","pages":"365-371"},"PeriodicalIF":3.5,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10798473","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143698302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In contrast to traditional approaches that typically utilize high-impedance structures with limited cancelation or antenna arrays employing null-steering techniques, which often result in increased complexity and cost, this study proposes the use of a single-element circularly polarized truncated microstrip patch antenna radially loaded by a magneto-dielectric metamaterial (MTM) structure. The problem is analytically examined, and an appropriate meta cell is chosen, designed, and fabricated.

Additionally, the random phase delays reduce the beam pointing error – a limitation of binary RISs - which can be beneficial in applications that require high resolution beam steering. The proposed topology allows for scalable RIS apertures that are compatible with printed circuit board (PCB) fabrication technology.

The antenna is designed to operate in the 24 GHz radar band and can be installed in field Internet of Things devices for vehicle monitoring and communication, meeting requirements for communication rate, sensing sensitivity, detection, and interconnectivity. The multibeam characteristic can effectively enhance the communication and sensing detection range of the antenna. Meanwhile, the grid-like structure of the antenna ensures good optical transmission, allowing it to be positioned above the solar panel without significantly affecting the performance of the solar cell. The measurement results show that the multibeam solar grid antenna can cover the 24 GHz radar band and achieve beam deflection in four azimuth planes with a gain range of 15.2 to 16.6 dBi at the center frequency of 24.125 GHz.

Despite their unique guiding properties, their use in real microwave devices is still in the early stages, lacking a comprehensive design procedure and comparative analysis with conventional guiding structures. To fill this gap, here we report a simple and straightforward workflow for designing waveguides supporting 1D modes propagation. The design is based on the analytical relations existing between the surface impedance of the propagating modes and the sheet impedance of the metasurfaces, which allow quick retrieval of the geometrical parameters of the complementary metasurfaces sustaining the line-wave propagation. This approach is used to design several waveguiding layouts and compare their transmission performance through full-wave simulations accounting for dielectric and ohmic losses. Finally, experimental results for some selected designs in the microwave regime are provided, and a thoughtful comparison between a line-wave waveguide and an equivalent microstrip transmission line is carried out to assess the suitability of these devices for efficient high-frequency waveguiding.","PeriodicalId":34267,"journal":{"name":"IEEE Open Journal of Antennas and Propagation","volume":"6 1","pages":"293-303"},"PeriodicalIF":3.5,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10767771","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143106975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
