To address this, a low-profile omnidirectional microstrip antenna integrated with three tailored absorbing structures (ASs) is proposed. The ASs are strategically embedded to efficiently dissipate incident wave energy, leading to significant reduction in both monostatic and bistatic RCS over the upper hemisphere. Equivalence theorem analysis reveals that the equivalent radiation current of the antenna and the scattering currents captured by the ASs are spatially orthogonal, thereby preserving good radiation performance. The proposed antenna operates at 3 GHz and has a diameter of 0.7λ<sub>0</sub> and a profile of 0.02λ<sub>0</sub>. It achieves average monostatic RCS reductions of 15.41 dB forϕ-linear polarization (LP), 14.55 dB (θ-LP), 11.09 dB for left-hand circular polarization (LHCP), and 11.08 dB for right-hand circular polarization (RHCP) within the angular range of 0° to 90°, together with effective wide-angle dual-LP and CP bistatic RCS suppression. Measured results agree well with simulations. The design maintains the same low profile as the reference antenna with only 0.31 dB gain loss, offering a combination of superior multipolarized, wide-angle, and high-level RCS reduction, making it well suited for stealth airborne applications.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"25 10","pages":"4003-4007"},"PeriodicalIF":4.6,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149124578","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}

Different from conventional filtering antennas employing separate filtering, feeding, and decoupling structures, the proposed filtering crossover functions as a multifunctional electromagnetic component that simultaneously realizes signal routing, filtering, dual-polarized excitation, and intrinsic port isolation. A quantitative modal-overlap evaluation framework is further introduced to and verify the orthogonality of the degenerate TM<inline-formula><tex-math>$_{110}$</tex-math></inline-formula> modes. A third-order prototype operating at 29.35 GHz is designed, fabricated, and measured. The measured results show an average gain of 6.76 dBi, a radiation efficiency of 93%, an out-of-band suppression exceeding 20 dB, and a port isolation better than 18 dB. Owing to the all-metal MISL implementation, the proposed antenna also features a compact low-profile structure, making it attractive for millimeter-wave dual-polarized front-end applications.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"25 10","pages":"4113-4117"},"PeriodicalIF":4.6,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149125532","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 metasurface unit cell adopts an H-shaped metallic structure composed of three patches with different dimensions, where the central gap is filled with a germanium telluride (GeTe) thin film. By applying multiple laser pulses, different local crystallization ratios are induced in the GeTe layer. To characterize the electromagnetic response under this nonuniform phase-transition state, an equivalent impedance model is established and validated. Simulation and measurement results demonstrate that the laser-induced metasurface exhibits multiple controllable impedance states, enabling multilevel amplitude reconfiguration. In the X band, simulations show that the reflection coefficient <inline-formula><tex-math>$|S_{11}|$</tex-math></inline-formula> can be tuned from −0.31 dB to −19.6 dB, while three representative laser-induced states are experimentally characterized to achieve three reflection levels of −8.2 dB, −4.5 dB, and −1.08 dB at 11.2 GHz. Benefiting from the nonvolatile phase-change behavior of GeTe and the laser-writing mechanism, the proposed metasurface requires no static power to maintain its reconfigured states and provides a promising platform for reconfigurable radar applications, including radar signature manipulation and false-target generation.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"25 10","pages":"4118-4122"},"PeriodicalIF":4.6,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149124579","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}
