By designing a checkerboard metasurface on the dielectric-barrier discharge (DBD) plasma substrate, the magnitude of waves reflected from the metasurface’s alternating tiles is effectively reduced. This improvement enhances tolerance to magnitude imbalance and enables more efficient destructive interference. The plasma-assisted checkerboard metasurface achieves an outstanding radar cross-section (RCS) reduction performance of up to 55.4 dB in the X-band for a plate with a <inline-formula> <tex-math>$200 times 200$ </tex-math></inline-formula> mm2 size experimentally, surpassing all previously reported methods. Theoretical analysis, simulations, and experimental findings align well, confirming the effectiveness of the proposed mechanism. This innovative use of plasma as a substrate, rather than a standalone medium, marks a significant departure from conventional plasma-based RCS reduction methods. This suggests the potential of plasma to push boundaries and create countless opportunities across a wide range of applications that can benefit from highly lossy substrates.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 4","pages":"2605-2614"},"PeriodicalIF":4.6,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143800984","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}

First, a polarization conversion unit cell and its rotated structure are applied to construct the 1-bit phase dartboard MSs (DMSs) for RCSR. The 1-bit phase DMSs achieve more than 10 dB monostatic RCSR at 4.1–17 GHz (122.3%) under the normal incidence of both linearly polarized (LP) and circularly polarized (CP) waves. Then, the Pancharatnam-Berry (P-B) phase generated by rotating the entire periodic polarization conversion unit cell array, which can eliminate the impact of coupling-related distortion in the unit cell array, is applied to construct the circular phased DMSs, which the phases of lattices are varied along the circular ring, for both RCSR and OAM wave generation under the far-field incident wave. The circular phased DMSs can achieve more than 10 dB monostatic RCSR at 4–17.1 GHz (124.2%) under the normal incidence of both LP and CP waves. Moreover, they also generate the OAM waves when illuminated by a CP wave. Finally, the circular phased DMS which can achieve RCSR and generate OAM wave with Mode 2 was fabricated and measured, and the measurement results are in good agreement with the simulation results.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 4","pages":"2497-2509"},"PeriodicalIF":4.6,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143800987","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}

First, the four-sides-shorted substrate integrated waveguide (SIW) cavity of the aperture antenna is selectively opened, and the opening position is investigated to ensure that the antenna performance is insensitive to the chip size. Then, an improved aperture antenna with the enhancements of the peak value and flatness of the antenna gain is introduced, and its resonant modes, performance improvement mechanism, and working principle are illustrated. Moreover, the stair-shaped package with side walls is established to support the chip, meanwhile, further gain enhancement can be achieved by manipulating the electric current distribution on the package. Finally, a prototype of the proposed antenna is fabricated and assembled, and measured results agree with the simulation. The improved performances with 5.7% bandwidth and 10.1 dBi gain are simultaneously obtained, which demonstrates it a good candidate for terahertz transceiver.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 4","pages":"2672-2677"},"PeriodicalIF":4.6,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143800970","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 antenna operates as a patch antenna in the MW band (2.4 GHz) and as a transmitarray (TA) in the MMW band (60 GHz). It was found that the transmitting surface (TS) of the TA can be equivalent to a MW patch at a large frequency ratio, and therefore, the two kinds of antennas can be tightly integrated and share the same radiating aperture through structure reuse. To accommodate the TA into the patch antenna, the TA is folded by adopting a polarization rotating surface (PRS), and its profile height is reduced to 1/3 of the focal length, which matches the profile of the patch antenna. Thanks to the spatial feeding architecture of the TA, the proposed antenna eliminates the need for a complicated feeding network and features low feeding loss and high gain in the MMW band. Additionally, the proposed antenna adopts a pair of differentially fed L-probes for the MW feeding network and a nondispersive stripline for the MMW TA, which contribute to the wideband performance of the antenna in both bands. To validate the design idea, a prototype is fabricated and measured. The experimental results show that it can achieve 3-dB gain bandwidths of 26.3% and 20.1% in the MW and MMW bands, respectively. It can be a promising solution for Wi-Fi/Wi-Gig applications.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 4","pages":"2485-2496"},"PeriodicalIF":4.6,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143800774","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}
