This design takes into account the reuse of different array surfaces and the reuse of different feed structures. By etching rectangular slots in the metallic ground of a receiver-transmitter structure, the low-band partially reflective surface and the high-band transmissive surface can be integrated into a single metasurface. Through this metasurface and a polarization conversion metasurface, the antenna hybridizes a Fabry–Perot cavity antenna (FPCA) at the sub-6 GHz band and a folded transmitarray (FTA) at the millimeter-wave (mmW) band. Furthermore, a planar dual-band feed structure is reused by incorporating slots into a microstrip patch and nesting a magneto-electric dipole. A dual-band shared-aperture antenna is designed, fabricated, and measured. Measured results demonstrate that the antenna achieves directional radiation performance in both bands under the condition of a cavity height of 0.51<italic>λ L. The measured peak gains in the sub-6 GHz and mmW bands are 14.5 dBi and 23.2 dBi, respectively. The overall antenna structure requires only two metasurfaces, offering advantages such as fewer layers, low profile, and a fully planar design.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"25 10","pages":"3843-3847"},"PeriodicalIF":4.6,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149124552","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}

To address this issue, this letter proposes a modular polyhedral-faceted hemispherical conformal array (PFHCA), where the hemispherical surface is approximated by planar facets to improve manufacturability while preserving wide-angle scanning capability. An efficient beamforming method based on carrier-level pattern reuse is developed by exploiting the identical radiation characteristics of elements on the same carrier. The proposed method reduces the computational complexity from O(<italic>N ) to O(<italic>M ), where M ≪⃒ N, and achieves an 11-to-19-fold speedup. Furthermore, a flexible excitation scheme with a flexibility factor <italic>α , combined with CMA-ES-based optimization, effectively suppresses sidelobe levels. A 2.45 GHz prototype is designed.

Two feed ports predominantly excite the TM10- and TM20-dominated modes, with an intrinsic field-phase contrast providing an approximately <italic>π relative phase over one half-space, enabling a radiation null to be formed through amplitude-only mode combination. The required modal weighting is realized via time-division switching with the duty-cycle ratio directly determining the effective carrier-frequency amplitudes, eliminating the need for analog RF attenuators and facilitating a simple digital control scheme with predictable and high-resolution null steering.

Structurally, the antenna comprises a pair of crossed-dipoles, two vacant-quarter rings (VQRs), four parasitic patches, four surrounding split rings, and twelve shorting posts. Notably, the parasitic patches and the shorting posts jointly constitute two sets of MEDs, the inherent low-frequency radiation zero (LRZ) of which is strategically positioned slightly below the inconspicuous LRZ brought by the crossed-dipoles with the VQRs. In this way, dual closely spaced LRZs are generated, helping achieve both satisfactory out-of-band suppression (OBS) and improved frequency selectivity in the lower stopband. Meanwhile, C-shaped slots are etched into the parasitic patches to generate a high-frequency radiation zero (HRZ), with the surrounding C-shaped split rings introduced to create an even higher-frequency radiation zero, further improving the OBS. Furthermore, truncated/filleted corners on parasitic patches/crossed-dipoles are implemented, greatly improving the CP performance. The measured results demonstrate an impedance bandwidth (IBW) of 71.5% (2.83 GHz to 5.98 GHz) and a 3 dB axial ratio bandwidth (ARBW) of 39.6% (3.65 GHz to 5.45 GHz), with stable radiation patterns achieved across the passband.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"25 10","pages":"4128-4132"},"PeriodicalIF":4.6,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149124524","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}

To reduce costs while improving data validity, we innovatively optimized the data collection with the aid of nondominated sorting genetic algorithm-II (NSGA-II). For the broadband design targets covering S, C, and X bands, low-frequency performance, total bandwidth, and in-band absorption are key concerns. Based on this background, we statistically analyzed three key indicators of −10 dB bandwidth from 1100 datasets acquired by different methods: the lowest frequency <italic>f low, the highest-to-lowest frequency ratio <italic>f high/<italic>f low, and the absorption depth. The dataset in this work has average values of 2.73 GHz for <italic>f low, 2.18 for <italic>f high/<italic>f low, and −15.74 dB for absorption depth. It outperforms the random dataset with 6.45 GHz, 1.53, and −14.14 dB, respectively. With the support of a high-quality dataset, we successfully trained and converged the deep neural network (DNN) model using only 1,100 data samples. By inputting a target broadband square-wave spectrum into the model, a broadband metasurface absorber is obtained, which achieves a −10 dB |<italic>S 11| bandwidth of 1.99 GHz to 12.47 GHz under normal incidence, and shows good oblique incidence stability. Experimental results verify that the proposed metasurface absorber exhibits excellent consistency between simulation and measurement.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"25 10","pages":"4063-4067"},"PeriodicalIF":4.6,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149124588","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}
