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 propagation characteristics in rainfall environments can be evaluated by analyzing the statistical characteristics of the 1-min cumulated rainfall rate. However, 1-min cumulated rainfall rate data cannot be directly obtained from most meteorological stations. Therefore, this study proposed a novel reconstruction method based on t-min cumulated rainfall rate to generate 1-min cumulated rainfall rate time series (CRRTS) such that the statistical minute rainfall rate can be obtained. A probability density function was constructed, and the constraint conditions at which the mean and standard deviation parameters were satisfied during CRRTS conversion were combined. The proposed method was used to analyze the 5-min cumulated rainfall rate data of Xi’an, Haikou, and Qingdao, collected in 2022, and the 1-min long-term statistical distribution characteristics were obtained. The results showed that the proposed model outperformed the ITU model and Emiliani model, confirming its feasibility and effectiveness.

The antenna consists of three folded structures: one narrow closed loop and two split loops. One of the split loops has a narrow width with its opening at the bottom, while the other split loop has a wider width with its opening at the top. The latter features folded PIFA-like structures. All these structures are connected in parallel and etched on a one-layer substrate. Due to the field’s cancellation, the design generates three radiation nulls near the passband, realizing filtering responses. The antenna achieves a measured −10-dB impedance bandwidth of 12.0% and exhibits omnidirectional radiation patterns. Its measured total efficiency within the passband is 87.4%, while the suppression level in the stopband exceeds 18.8 dB. This basic omnidirectional filtering design is extended to multiple input multiple output (MIMO) array designs. By loading decoupling meander lines between closely spaced elements (<inline-formula> <tex-math>$lt 0.02lambda _{0}$ </tex-math></inline-formula>), port isolations are increased by over 9.6 dB. Moreover, the distorted radiation patterns are significantly improved. A prototype of the <inline-formula> <tex-math>$1times 4$ </tex-math></inline-formula> MIMO array was fabricated and tested to verify the idea. A reasonable agreement between measured and simulated results was obtained. This MIMO array has couplings lower than −19.8 dB with rectangular coefficients below 1.35.

First, two algorithms (CRICO-I and -II) are introduced to reduce the time cost of synthesizing UWB arrays by reasonably selecting the decreased sidelobe constraints. Specifically, the CRICO-I adaptively chooses the sidelobe region that corresponds to lobes with high peak level as the sidelobe constraint domain, and the CRICO-II selects the sidelobe region above a prescribed threshold level as the sidelobe constraint domain. Other sidelobe constraints outside the selected sidelobe constraint domain are removed. In addition, a few refined steps are performed in which array layouts are successively optimized in each step, where the UWB array’s pattern is renewed by multiplying the array factor with currently updated element positions and the active element patterns (AEPs) obtained in the previous refined step. In such a way, the MC effect is incorporated into the synthesis process. Two examples of synthesizing UWB beam-scanning linear and planar arrays with different array sizes and beam-scanning ranges are conducted. Synthesis results validate the good efficiency and grating lobes (GLs)/sidelobes’ suppression performance of the proposed method for UWB beam-scanning aperiodic antenna array synthesis.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 8","pages":"6038-6043"},"PeriodicalIF":5.8,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144782061","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}

A polarization conversion unit cell, capable of receiving linearly polarized (LP) incidence and transmitting CP radiation, is first designed. Based on the geometric phase (GP) compensation strategy, a full 360° transmission phase with good CP radiation performance is achieved by rotating the transmitting element. Moreover, the quad-focal phase compensation scheme is implemented to construct the GP phase distribution required by 2-D beam scanning to minimize the scanning loss of the transmitarray. To lower the SLL during large-angle beam scanning, the multiobjective particle swarm optimization (MOPSO) algorithm is further employed to refine the phase distribution across the transmitting layer. For validation, a fully functional prototype of the proposed transmitarray illuminated by a movable LP horn is fabricated and measured. The measured results show a wide overlapped 3-dB gain and axial ratio (AR) bandwidth of 26% with a peak gain of 21.5 dBic. Besides, the measured SLL remains below −11.4 dB within a scan range of ±34° in two orthogonal planes.
