The main concept involves manipulating the current distribution of a loop resonator to convert linearly polarized incident waves into cross-polarized waves upon reflection. The RPR consists of three metal layers separated by two dielectric substrates, featuring a square loop on the top layer and a folded strip line in the middle layer connected by vias. Multiband operation can be achieved by adding extra loops to the top layer, with each loop controlling its own frequency band. As a proof of concept, a dual-band RPR was designed using two square loops on the top layer operating in the [2.02 to 2.26] GHz and [4.12 to 4.48] GHz ranges. The design was extended to a tri-band by adding a third loop, operating at [1.54 to 1.7] GHz, [3.35 to 3.7] GHz, and [5.1 to 5.45] GHz. Thorough discussions of current distribution analysis, and experimental demonstrations are provided. The simulated results are validated through prototype measurements, showing good agreement with experimental data.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"24 9","pages":"2934-2938"},"PeriodicalIF":4.8,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144998320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 widely used mutual coupling model is linear and cannot describe the direction-dependent characteristics of mutual coupling, which leads to serious performance deterioration of array signal processing algorithms. In this letter, a new nonlinear mutual coupling model named high-order broad mutual coupling matrix (MCM) is established based on the Taylor expansion to describe the directional-dependent coupling relationship between two adjacent antenna elements. Then, an accurate parametric analytic manifold using a finite-order approximation of the high-order broad MCM is yielded by the antenna pattern reconstruction method. Numerical examples verify that the array manifold reconstruction errors can be reduced exponentially by the proposed parametric analytic manifold. Especially when the piecewise fitting strategy is adopted, the reconstruction errors of the fourth-order approximated analytic manifold can be reduced to less than 1% of those of the conventional array manifold.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"24 9","pages":"2904-2908"},"PeriodicalIF":4.8,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144998129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent research has extensively explored graphics processing unit (GPU)-based parallel implementations of the FDTD method to enhance computational performance. However, the inherent time-stepping and time-marching nature of the FDTD algorithm leads to frequent kernel launches and low memory efficiency on GPUs, still significantly impacting execution efficiency. This letter proposes a GPU-based FDTD framework enhanced with operator fusion to address this challenge. Within this framework, the FDTD algorithm is represented as a computation graph composed of operators. We classify these operators into different types based on their input and output relationships. Using this type of information, a rule-based strategy is developed to merge the operators into larger computational kernels, effectively enhancing GPU execution efficiency. Simulation results demonstrate that the proposed operator fusion framework does not introduce additional errors while achieving a 4× speedup compared to conventional GPU-based implementations.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"24 9","pages":"2914-2918"},"PeriodicalIF":4.8,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144998221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 novelty of the proposed design is achieving a gain of approximately 20 dBi from single unit cell lens SIW antenna. The proposed 4 × 4 multiple-input–multiple-output (MIMO) SIW lens achieves a high isolation above 30 dB for the operating band with high gain. The proposed MIMO SIW lens antenna achieves a −10 dB bandwidth of 1.1 GHz (27.89 GHz to 29 GHz). It is achieved by a pair of parallel slots on top of the SIW cavity. The proposed design offers a simulated gain of 6.5 dBi, which was then enhanced to 18.5 dBi at 28.4 GHz with the integration of a 3-D-printed dielectric homogeneous lens. The cavity-backed lens antenna is used to realize a 4 × 4 MIMO antenna structure. The 4 × 4 MIMO SIW lens antenna has isolation above 30 dB (between the four antenna elements) throughout the frequency band of operation. The measured results are in good agreement with Ansys HFSS simulations. The stable antenna performance makes it suitable for applications in satellite, radar imaging, and point-to-multipoint wireless communications.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"24 9","pages":"2889-2893"},"PeriodicalIF":4.8,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144998369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
