In response to these limitations, a rapid design framework is developed by combining the discrete dipole approximation (DDA) with a physics-aware polarization-coupled hybrid network (PA-PCHN). A dedicated DDA-based solver is constructed and systematically validated through comparison with full-wave electromagnetic simulations. As a result, the per-evaluation computational time is reduced from 15 to 20 min to approximately 2–3 s, which enables efficient generation of large-scale training datasets. The proposed PA-PCHN integrates Transformer-based global feature extraction with angular-domain convolutional decoding, complemented by a bidirectional cross-attention mechanism, enabling rapid and accurate prediction of full-angular complex CP far-field electric fields. Building on the surrogate model, a hybrid simulated annealing–genetic algorithm (SA–GA) is employed to jointly optimize multibeam formation, sidelobe suppression, and axial ratio performance. Several antenna prototypes operating at 5.8 GHz are fabricated and experimentally characterized. The measured results exhibit good agreement with simulations, confirming that the proposed approach substantially enhances design efficiency without compromising accuracy and is well-suited for large-scale antenna array optimization.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"74 10","pages":"9326-9338"},"PeriodicalIF":5.9,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149131700","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 proposed approach employs Goldberg polyhedron topologies for the array and field matching techniques for the lens elements. Initially, a system-level optimization is performed for directivity, beam overlap, and interference using cost functions based on analytically computed antenna radiation patterns. This provides the optimal Goldberg spherical topology for a number of unique antenna elements in the array and their required aperture current distribution. Two antenna system examples are introduced in this process. The first achieves a −3 dB uniform beam overlap for full-hemispherical coverage. The second includes interference analysis for a full multibeam communication scenario. The optimal current distributions of the array’s unique elements obtained by the optimization of the Goldberg topology can, in turn, be synthesized via a core-shell lens antenna whose geometry is derived using a field matching technique. Three lens antenna designs are presented. These employ different lens shaping techniques and reach highly suppressed far-field side lobe level (SLL). The element design process and array topology are validated using full-wave simulations of the unique antennas.

This article presents an in-depth study of the mid-latitude wideband HF ionospheric channel from measurement and modeling to characterization and application. First, a measurement system based on a universal software radio peripheral (USRP) with an ionospheric channel-adapted data processing scheme is utilized to achieve high-precision extraction and clustering of the multipath components in the channel impulse response (CIR). Second, a comprehensive dynamic channel model is constructed, consisting of a time–frequency-correlated dynamic large-scale fading model and a dual-propagation-mode small-scale fading model based on the statistical distribution properties of the parameters. Finally, wideband HF ionospheric channel characteristics such as fading characteristics, level crossing rate with average fading duration (AFD), and time-varying signal-to-noise ratio (SNR) are analyzed in depth. The research results not only enrich and improve the channel model of wideband HF ionosphere but also provide guidance for the design and optimization of reliable communication systems in this scenario.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"74 10","pages":"9815-9830"},"PeriodicalIF":5.9,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149131884","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}

Another crossed structure with minor phase perturbance is further introduced to form the modified multiple element for improved axial ratio (AR) performance. Subsequently, a CP endfire helical LWA is constructed by periodically arranging such modified multipole elements.

For arrays with <inline-formula> <tex-math>$N = PQ$ </tex-math></inline-formula> elements, the Butler matrix factorization is shown to correspond exactly to the factorization of the array factor (AF) into a fine contribution from sparsely populated subarrays and a coarse contribution from their phase centers.

The analysis also identifies parity-dependent solvability conditions and introduces a generalized phase-correction scheme that resolves previously overlooked pointing ambiguities. The resulting interpretation provides an intuitive, analytically rigorous, and scalable methodology for multibeam array and Butler matrix design.
