However, their practical deployment is hindered by varying divergence characteristics across vortex modes with different mode numbers. To overcome this challenge and enable true spatial multiplexing of orbital angular momentum (OAM) waves, a dual-polarized shared-aperture metasurface is proposed. By leveraging both polarization and OAM multiplexing, quasiperfect vortex (QPV) EM waves with coaxial beams and equal divergence radii are successfully generated at microwave frequencies. Initially, the properties of QPV waves in the microwave band are analyzed, followed by the design of a dual-polarized metasurface unit. This unit integrates parasitic damping-coupled patches based on the traditional Jerusalem cross structure, providing polarization-independent control and approximately 360° phase-tuning capability. Furthermore, simulations validate the effectiveness of the dual-polarized single-mode metasurface design. Based on this, the concept is extended to a 4-channel multiplexing metasurface, operating at 15 GHz and capable of generating QPV waves. Finally, experimental results from the fabricated metasurface demonstrate the generation of QPV waves with OAM mode numbers 0, +2, +1, and −1, achieving simulated and measured OAM mode purities of 0.835 and 0.70, respectively. The experimental data closely aligns with simulations, confirming the effectiveness of the design. This study offers new insight into generating and applying perfect vortex EM waves, paving the way for high-capacity near-field wireless communication systems and advanced control of novel EM physical dimensions.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 7","pages":"4583-4594"},"PeriodicalIF":4.6,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144598053","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}

Moreover, by co-design and including air vias (AVs) for the surface-wave aperture, the structure becomes semi-transparent and can be positioned on top of solar panels, and this can improve solar power harvesting capabilities. Structure excitation is made possible by a leaky T-junction dual-feeder using substrate-integrated waveguide (SIW) technology, creating a uniform wavefront that propagates through a truncated parallel-plate waveguide (PPW) section. In addition, a matching section based on an array of subwavelength printed patches is also included at the interface between the PPW and the grounded dielectric slab (GDS), while the AV section is positioned between the GDS and air region to improve antenna radiation. These features allow for an efficient and compact aperture, and findings are competitive compared to other relevant structures. For instance, the measured prototype demonstrated a peak realized gain (RG) of 17.5 dBi at 18.6 GHz, as well as high radiation efficiency and sidelobe levels (SSLs) of about −10 dB. This makes the SWA suitable for high data rate downlink communications when nondeployable designs are required on CubeSats, for example, or wherever a low-profile, simple, and planar antenna is needed with radiation directly at endfire.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 6","pages":"4086-4091"},"PeriodicalIF":4.6,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144219627","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 design employs active feeds fabricated utilizing 40-nm CMOS technology. A passive transmitarray is designed based on cost-effective printed circuit board (PCB) technology. In the active feed section, high-power direct up-conversion active transmitter circuits are utilized alongside higher-order mode dielectric resonator (DR) antennas to significantly enhance the effective isotropic radiated power (EIRP) while facilitating communication functions. The passive transmitarray section incorporates a novel concept of power-combining transmitarray, overcoming the conventional limitations of two-way power combining and feed spacing being less than half the wavelength. This technique enables watt-level output while maintaining the low cost and high integration. The measured maximum EIRP reaches 35.2 dBm at 140 GHz, marking a 25.4 dB increase over a single active feed. Consequently, this active antenna achieves a data transmission rate of 48 Gb/s.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 7","pages":"5005-5009"},"PeriodicalIF":4.6,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144597960","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}

However, the ring-up/down process requires a prolonged duration due to the narrowband characteristics of a high-Qm ME antenna, which causes severe intersymbol interference (ISI) and significantly limits the data transmission rate when conventional modulation schemes [e.g., amplitude shift keying (ASK)] are adopted. In this work, we propose a predistortion waveform design to suppress the ISI when transmitting a bitstream with high symbol rate for a narrowband ME antenna. Different from the arbitrary waveform design without any constraints, we limit the peak voltage of the predistortion waveform three times the level of the stable value after considering an economic power amplifier design. Accordingly, a modified binary ASK (modified BASK) modulation scheme is established. Experimental and simulation results show that modified BASK achieves a fivefold bandwidth improvement with only a 20% reduction in efficiency. Experimental results show that reliable communication rate based on the proposed waveform design can reach 1000 bps at a 15 m communication distance, while the counterpart for conventional BASK method is only 500 bps with 10 m distance. The proposed predistortion waveform and the established modulation method circumvent the mutual limitation between the information bandwidth and the physical bandwidth for a very-low frequency (VLF) mechanical antenna and are believed to speed up the communication application for ME antennas in VLF band.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 7","pages":"4409-4420"},"PeriodicalIF":4.6,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144598061","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}
