The method utilizes the surface susceptibility model (SSM), a parametric model of metasurfaces, in conjunction with geometrical optics (GO) and physical optics (PO). The study showcases that through the utilization of this technique, targets comprised of metasurfaces can be accurately and efficiently analyzed on standard computers. This level of precision and efficiency is challenging to achieve with traditional GO/PO and brute-force analysis methods, making this approach particularly beneficial for large systems where metasurfaces are a component of the scattering analysis. To test the accuracy, flexibility, and performance in scenarios involving multiscattering, a uniform array, a gradient array, and a dihedral corner reflector constructed from two metasurface arrays are evaluated. The results are validated using commercial software for both the s (or TE) and p (or TM) polarization, confirming the high efficiency and flexibility of the proposed method.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 1","pages":"671-676"},"PeriodicalIF":4.6,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143106632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current methods to achieve non-<inline-formula> <tex-math>$2^{n}$ </tex-math></inline-formula> ports are mainly based on additional power distribution networks or modifications of the directional coupler, resulting in larger sizes and higher insertion loss. This article presents a generalized design procedure of the Butler matrix with arbitrary positive integer beams, including arbitrary non-<inline-formula> <tex-math>$2^{n}$ </tex-math></inline-formula> beams, based on the fast Fourier transform (FFT) algorithm. By making the transmission matrix of the Butler matrix equal to the target matrix, the parameters of each device in the network structure can be determined. Thanks to the feature of the FFT, the proposed Butler matrix structure is compact, and the design procedure is general. The design procedure of Butler matrices for <inline-formula> <tex-math>$N = 5$ </tex-math></inline-formula>, 6, and 7 is presented as examples. To show the effectiveness of the proposed procedure, a prototype of the Butler matrix operating at the Ku-band is designed and fabricated to feed an array. The E-plane waveguide feed network is used to achieve low insertion loss and small size. The measured S-parameters are better than −10 dB, the insertion loss is less than 1.2 dB, the phase imbalance is ±8.3°, and the steering angles are 0°, ±22°, and ±46°, respectively.

Coupled with a large synthetic dataset of antenna field maps and novel magnitude and phase loss functions, we develop an NF super-resolution network (NFS-Net) to reconstruct significantly undersampled NF data into high-resolution data. This approach considerably reduces the number of sampling points required for NF measurement and thus improves measurement efficiency. The high-resolution NF data reconstructed by the network are further processed by a near-field-to-far-field (NF2FF) transformation to obtain far-field (FF) antenna radiation patterns. Our experiments demonstrate that the NFS-Net exhibits both accuracy and generalizability in restoring high-resolution NF data from low-resolution input. The NF measurement workflow that combines the NFS-Net and the NF2FF algorithm enables accurate radiation pattern characterization with only 11% of the Nyquist rate samples. Though the experiments in this study are conducted on a planar setup with a uniform grid, the proposed method can serve as a universal strategy to accelerate measurements under different setups and conditions.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 3","pages":"1732-1742"},"PeriodicalIF":4.6,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143553491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The digital conformal array consists of a 1-bit multimode radiator, metasurfaces, and switch designs. By manipulating the field distributions of the transmission line (TL), a miniaturized multimode radiator is explored. Next, a low-cost 1-bit planar digital array without any feeding networks is proposed by coding the 0°/180° phase states of each mode/element. To match the circular/cylindrical/spherical scenarios, the planar digital array evolves into a conformal format. Here, to further lower the complexity and cost, the spatial phase difference of the digital conformal array is cleverly compensated by utilizing a metasurface layer rather than conventional phase-delay-line designs. By controlling the 1-bit phase states of each element, the radiation aperture of the digital conformal array is represented as a “0/1” binary sequence, which leads to an RIS-like multibeam switching capability. Moreover, by introducing the initial phase, a new 1-bit digital array with a single-beam steering capability is extended to further explore its application potential. To validate the concept, a four-element 1-bit digital conformal array was fabricated and measured. The digital conformal array could achieve a −10 dB impedance bandwidth of 4.74–5.12 GHz (7.7%) and a peak gain of 11.0 dBi, which makes it a good candidate for intelligent wireless communication and detection applications.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 3","pages":"1523-1536"},"PeriodicalIF":4.6,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143553498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The 1-bit active coding is designed based on the current reversal method, which realizes two states with 180° phase difference over the frequency range of 8.5–11 GHz by switching two p-i-n diodes for both left-handed CP (LHCP) and right-handed CP (RHCP) incidence.

However, acquiring radio channels in practical deployment scenarios and replaying recorded channels in the laboratory setup, which is the essence for the VDT framework, still present significant challenges. Passive channel sounding, which can capture radio channels in the live cellular network, becomes a promising strategy. However, channel modeling and emulation based on data collected in passive channel-sounding campaign have not been well addressed in the state-of-art. In this work, we propose a novel channel modeling and emulation framework for the recorded channel data by the passive channel sounder, to achieve the VDT purpose. To demonstrate our proposed framework, a channel measurement campaign was conducted in the fifth-generation (5G) commercial network based on the home-developed passive channel sounder. The estimated multipath components based on the recorded channel data demonstrate that the base station (BS) beamforming can significantly impact the radio channels. The performance of different commercial user equipment (UE) is then evaluated under the recorded and emulated radio channels in the laboratory setup, where different figures-of-metrics (FoMs), including reference signal receiving power (RSRP), modulation and coding scheme (MCS), and throughput, were thoroughly analyzed. The experimental results clearly demonstrate the feasibility of the proposed VDT framework in the laboratory setup.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 3","pages":"1777-1791"},"PeriodicalIF":4.6,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143553473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
