Unlike conventional moving-matter systems, modulation systems do not involve any net motion of matter and are therefore easier to implement and capable to attain relativistic and superluminal velocities. However, the fundamental wave-medium interaction aspects in such media, such as scattering and energy-momentum relations, have been essentially unexplored to date. In this article, we fill this gap, considering three dynamic systems: moving-matter blocs, moving-perturbation interfaces, and moving-perturbation truncated periodic structures, and provide corresponding general formulations along with comparisons. Our investigation reveals significant roles played by the “pushing” and “pulling” effects of the moving interface onto the wave in such systems. Moreover, it describes different energy and momentum transfers between moving media and homogenized moving-perturbation structures that result from conventional and reverse Fresnel-Fizeau drag effects.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 7","pages":"4780-4794"},"PeriodicalIF":4.6,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144597969","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 antenna structure can produce true efficiency zeros (EZs) at both sides of the operating band across the beamwidth, not restricted to the boresight. The filtering antenna comprises three coupled radiators. The driven inverted-F radiating element is directly excited from the port, while the other two parasitic radiators are excited through electromagnetic coupling with the driven radiator. By controlling the resonant frequencies and the coupling relationships, a transversal filtering antenna (TFA) with a third-order filtering response is realized with all quarter-wavelength radiators. The antenna exhibits an EZ on each side of its passband, significantly enhancing its selectivity and thereby enabling the suppression of interference from out-of-band signals. The design method of the proposed filtering antenna is presented. Some design guidelines are provided. Without increasing the antenna footprint, the techniques introduced in this work are not only helpful for improving selectivity but also very useful for bandwidth enhancement of conventional unbalanced antennas. To validate this technology, an antenna for the 5G new-radio (NR) frequency band is designed, fabricated, and measured. The experimental results align very well with the simulations. To evaluate the out-of-band interference suppression, a dual-antenna system was constructed and tested, with one antenna operating at the NR band (3.3–5 GHz, 42%) and the other antenna operating at the Wi-Fi band (5.15–7.125 GHz, 32%). Test results demonstrate excellent out-of-band decoupling up to 20 dB within the near stopband, showing promises for space-limited terminal applications.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 7","pages":"4262-4273"},"PeriodicalIF":4.6,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144598048","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}

In this communication, we prove that spoof surface plasmon polaritons (SSPPs) and periodic mode-modulation methods can be used to solve this problem. The proposed dual-band mode-modulated leaky wave antenna (LWA) consists of modified substrate-integrated coaxial lines and microstrip lines based on the SSPPs transmission line (TL). The strong dispersion effect of SSPPs allows the LWA not only to satisfy the −1st harmonic radiation in the low band, but also to realize the −2nd harmonic radiation in the high band. Because two discontinuities of each mode-modulation period form a pair of reflected waves naturally that can cancel each other, the proposed LWA can suppress the open-stopband (OSB) effect in two bands simultaneously with the rare dual-band continuous beam-scanning capability. Besides, the slow wave effect of the SSPPs counteracts the gradual increase in radiated energy with the frequency of the LWA, resulting in more stable leaky wave radiation. Experiment results confirm that the proposed DB-LWA can realize −81° to 42° and −44° to 5° continuous beam scanning in two bands (7–12.8 and 14–16.1 GHz), respectively, with the gain stability of 0.13 and 0.19, respectively.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 6","pages":"4170-4175"},"PeriodicalIF":4.6,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144219733","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 antenna adopts the loop multimode resonant technology and the odd-even mode feeding technology. By exciting the first three modes of the loop of the watch frame, the effective resonance at 2.5, 4.4, and 5.8 GHz is achieved. The polarization diversity technology on the common aperture is realized through the odd-even mode feeding technology. Therefore, the orthogonal current directions are generated within the watch frame, and the watch strap is efficiently used for the diversity at 0.82 GHz, for n5, n41, n79, and industrial, scientific, and medical (ISM) band applications. Simulations and measurements from the watch antenna showed excellent performance in terms of reflection, far field, and polarization diversity. Besides that, additional evaluation on the human wrist also indicates low specific absorption ratio (SAR) and envelope correlation coefficient (ECC) levels. To the best of our knowledge, such multiband diversity antennas with favorable characteristics designed for watches are not evident in other state-of-the-art literature.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 7","pages":"4286-4299"},"PeriodicalIF":4.6,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144597617","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}
