(The alternative mode being the production of yearly rain attenuation statistics.) Such extension is to the 2-D case with a validity limitation to distances not too far from where the input rain rate recording has been made. This is possible thanks to the fact that we are interested in slant links where the path length subjected to rain is only of a few km. Similarly, this technique would be valid for short terrestrial paths. We need to bring in the second dimension: we are interested in site and orbit diversity simulations involving spaced locations and/or converging links. We introduce the simultaneous modeling of rain at different, not too far off, locations by taking into consideration the Gaussian multivariate characteristics of the natural logarithm of rain rate fields. Spatial effects, thus, introduced are achieved with the addition of realistic (even nonisotropic) cross-correlation functions.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 5","pages":"3257-3269"},"PeriodicalIF":4.6,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10875993","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143925230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The antenna operates as a patch antenna in the MW band (2.4 GHz) and as a transmitarray (TA) in the MMW band (60 GHz). It was found that the transmitting surface (TS) of the TA can be equivalent to a MW patch at a large frequency ratio, and therefore, the two kinds of antennas can be tightly integrated and share the same radiating aperture through structure reuse. To accommodate the TA into the patch antenna, the TA is folded by adopting a polarization rotating surface (PRS), and its profile height is reduced to 1/3 of the focal length, which matches the profile of the patch antenna. Thanks to the spatial feeding architecture of the TA, the proposed antenna eliminates the need for a complicated feeding network and features low feeding loss and high gain in the MMW band. Additionally, the proposed antenna adopts a pair of differentially fed L-probes for the MW feeding network and a nondispersive stripline for the MMW TA, which contribute to the wideband performance of the antenna in both bands. To validate the design idea, a prototype is fabricated and measured. The experimental results show that it can achieve 3-dB gain bandwidths of 26.3% and 20.1% in the MW and MMW bands, respectively. It can be a promising solution for Wi-Fi/Wi-Gig applications.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 4","pages":"2485-2496"},"PeriodicalIF":4.6,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143800774","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}

Standard Doppler analysis estimates signal distortions by assuming that all objects in the system travel at a constant velocity. The increasing speed and complexity of modern systems, however, requires an understanding of how the general 3-D motion of the sensor distorts the signal. In this work, we establish and interpret the spectral perturbations caused by changes in speed, i.e., acceleration and jolt, and by changes in the direction of velocity, i.e., the 3-D geometry of the receiver path, which together form the building blocks of arbitrary nonlinear motion. For constant jolt, the transmitted signal is distorted by a nonlinear chirp, which results in nonuniform spectral broadening and can create Airy-type oscillations in the amplitude spectrum. We identify sensor path approximations that incorporate the nonlinear phases induced by the 3-D geometry: the helical and Frenet-Serret approximations, which result in sinusoidal and cubic phase signals, respectively. We characterize the dependence of the spectrum on curvature, torsion, and the relative direction of wave propagation to the Frenet-Serret frame.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 3","pages":"1840-1845"},"PeriodicalIF":4.6,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10858678","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143553076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We simulate a nearly perfect, lossless RIS, and a realistic lossy anomalous reflector (AR) in a ray tracer and analyze the large-scale fading of simple RIS-assisted links. We also compare the results with continuous and quantized unit cell reflection phases with 1–4-bit resolutions. Finally, we perform over-the-air communication link measurements in an indoor setting with a manufactured sample of a wide-angle AR. The EM, system-level, and RT simulation results show good agreement with the measurement results. It is proved that the introduced macroscopic model of an RIS from the EM aspects is consistent with our proposed communication models, both for an ideal RIS and a realistic AR. The verified system-level simulator and ray tracer for an RIS could be tailored to, e.g., the wireless communication system engineers in the cellular network planning business, providing tools to optimize the network performance.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 3","pages":"1756-1767"},"PeriodicalIF":4.6,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10858656","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143553501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
