The volumetric mesh generates a large impedance matrix and results in a time-consuming eigenvalue equation-solving process. Skeletonization is employed to improve the efficiency of the VIO-based method by leveraging the rank-deficient property. Both the memory and time required for assembling impedance matrices are significantly reduced. The repeated matrix-vector multiplications involved in solving the eigenvalue equation are expedited. Numerical examples are presented to validate the accuracy and efficiency of the proposed method. Parameter optimization is performed to achieve a more practical and efficient algorithm setting.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"24 9","pages":"3218-3222"},"PeriodicalIF":4.8,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144998321","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}

However, these arrays often suffer from serious cross-band coupling, leading to deterioration in radiation performance. This letter proposes a novel balun integrated with miniaturized open-circuited stubs. By cascading multiple quarter-wavelength open stubs and strategically bending them to fit the maximum width, the proposed balun introduces transmission zeros that provide filtering capability for electromagnetic interference from other frequency bands. An equivalent circuit model is then developed to facilitate the integration of the balun with the antennas. With the novel miniaturized filtering balun and the equivalent circuit model, a triple-band antenna array for the fifth-generation base stations is developed. A prototype is fabricated and measured to validate the effectiveness of the proposed approach. Measured results illustrate that the isolation between the low-band (0.69 GHz to 0.96 GHz) and middle-band (1.90 GHz to 2.70 GHz) is improved from 18.0 dB to 32.0 dB in the middle-band, and the isolation between the low-band and high-band (3.30 GHz to 3.90 GHz) is improved from 25.0 dB to 36.0 dB in the high-band.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"24 9","pages":"3248-3252"},"PeriodicalIF":4.8,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144998039","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}

Using the receive-and-transmit method, the reconfigurable TA (RTA) element is designed by combining two reconfigurable magnetoelectric (ME) dipole antennas. PIN diodes are integrated in the RTA element to control the current path. Hence, the receiving and transmitting layers can independently provide a 90° and 180° phase shift to achieve the 2-bit resolution. Furthermore, a novel prephase distribution is introduced in the TA aperture to suppress the cross-polarization levels. As a demonstration, a wideband electronically RTA with 11 × 11 elements is designed, fabricated and measured. The measured results show the prototype can achieve a 3 dB gain bandwidth of 32%, a peak gain of 21 dBi, and a peak aperture efficiency of 37%. The measured cross-polarization levels are suppressed lower than 20 dB. Moreover, the proposed RTA can support the wide scanning angles from −50° to +50° in both E- and H-planes within the operating bandwidth.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"24 9","pages":"3238-3242"},"PeriodicalIF":4.8,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144998384","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 selection of the state of each RIS cell, commonly referred to as the “codebook,” can be made similar to array design, assuming that the far field of the RIS is a weighted combination of the far fields of individual cells. However, the full-wave analysis of even a 1-bit RIS geometry reveals that mutual coupling between cells strongly affects the scattered fields of the RIS, creating a wide range of realizable scattering patterns. We show that a computationally efficient, mutual coupling aware model of RIS scattered fields (empowered by a convolutional neural network) enables the exploration of these patterns by an optimizer, to meet design objectives beyond those achievable by standard codebook optimization approaches. Moreover, we demonstrate the design of 1-bit RIS codebooks that are free of spurious (“quantization”) lobes—a problem that was previously resolved only by modifying the RIS unit cells, increasing their complexity.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"24 9","pages":"3188-3192"},"PeriodicalIF":4.8,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144997982","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}
