The suggested MIMO antenna functions at 2.45 GHz and occupies a volume of 4.7 mm × 4.5 mm × 0.12 mm, making it among the most compact designs reported in this category. Size reduction is achieved using meandered lines. The proposed MIMO antenna consists of dual radiating elements sharing the same ground plane and are spaced 0.5 mm apart. Designed for implantation at a depth of 30 mm within the anatomical environment of the human heart, it is a promising candidate for leadless pacemaker applications. The antenna was fabricated and tested, achieving an isolation greater than 22 dB, which confirms excellent MIMO characteristics. Key parameters, including the envelope correlation coefficient and diversity gain, were also evaluated and exhibited favorable values, ensuring reliable MIMO operation. It exhibits omnidirectional radiation with spatial diversity. Specific absorption rate evaluation is conducted using a human tissue environment to verify compliance with safety standards. The results validate the antenna's suitability for implantable applications.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"25 4","pages":"1842-1846"},"PeriodicalIF":4.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147665181","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, imaging dynamic and nonsparse scenes using information metasurfaces remains challenging. To address this issue, we present a joint multiframe superresolution reconstruction approach for video imaging using information metasurfaces. By leveraging the ultrafast code-switching capability of information metasurfaces, we formulate the video imaging problem as a joint multiframe superresolution reconstruction task. Furthermore, by exploiting the temporal correlation of the background and the sparsity of dynamic variation across multiple frames, we introduce a low-rank and sparse decomposition with interframe smoothness model for the superresolution reconstruction. An effective algorithm based on the proximal gradient method is developed to solve the proposed model, enabling high-resolution imaging of dynamic and nonsparse scenes. Simulation results demonstrate that the proposed approach achieves superior reconstruction performance compared to the existing computational imaging methods.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"25 4","pages":"1792-1796"},"PeriodicalIF":4.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147665373","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 achieve this goal, this letter presents a novel method of designing a millimeter-wave phased array based on unidirectional wide-beam monopole elements. The antenna is composed of a monopole radiator fed by a coplanar waveguide, a reflector, and two grounded U-shaped patches with shorting pins. In order to realize wide beamwidth and high cross-polarization discrimination, a magnetic current is introduced by a current loop flowing along the path of the shorting pins and the reflector. Hence, the term, “MagnetoElectric Monopole,” is given to represent the novel antenna. Far-field radiation by the currents on the two grounded U-shaped patches cancels each other, so the cross-polarization is reduced. Combining the magnetic current and the electric current on the monopole contributes to a wide beamwidth. A metasurface consisting of periodic patches is designed to reduce mutual coupling for the phased array. The prototyped array has measured scanning angle of ±80° with small scan loss of 1.7 dB in 24 GHz to 30 GHz. The simulated cross-polarization level is less than −19.4 dB during the scanning process.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"25 4","pages":"1832-1836"},"PeriodicalIF":4.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147665425","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}

Furthermore, the time-modulated resonators are realized by the pentagonal SIW cavity loaded with a time-modulated varactor. Two static resonators are realized by rectangular SIW cavities connected by Tx and Rx ports, while the other one is realized by a square cavity integrated with the slot antenna.

Particularly, the capability to implement these applications in scattering channels represents a significant stride forward. This letter proposes a time-reversal multifocusing theory applicable to metallic scattering and low-loss dielectric scattering channels. To validate the theoretical framework, we introduce a time-reversal-based metasurface capable of controlling the amplitude and phase, enabling high-efficiency multifocusing in metallic scattering and low-loss dielectric scattering channels with controllable intensity ratio across different focal points. The adaptability of the proposed intensity-controlled metasurface is demonstrated through full-wave simulations and measurements in two representative scattering channels. Ultimately, the proposed metasurface achieves high-precision multifocusing in various scattering channels, with controllable intensity for each focal spot, and extends to a broader frequency range (5.2 GHz to 6.4 GHz) with high focusing efficiency (48% to 64%). Furthermore, we developed a measurement for intensity-controllable dual-focusing WPT utilizing the time-reversal multifocusing metasurface in scattering environments.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"25 4","pages":"1837-1841"},"PeriodicalIF":4.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147665460","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}
