A meander line concept has been utilized in the radiator section to lower the antenna size. The lateral dimension of the PPLPMDA antenna is smaller by 36.65% and the horizontal dimension is smaller by 10% extra space here? compared to the conventional planar log-periodic dipole array antenna. The patches have been included for certain dipoles to get a high and nearly stable gain in the entire operating frequency range. The fabricated PPLPMDA antenna is tested in terms of S-parameters, far-field radiation performance, IEMI sensing, etc., and witnessed good agreement between simulation and measurement results.

However, CM filters based on the well-known LC low-pass filter are usually bulky and costly. Many solutions to this problem have been proposed based on active filter technologies, which have the major drawback of requiring the use of current detectors, active circuits, and auxiliary power supplies. Therefore, a passive CM current cancellation method is proposed that is composed entirely of passive components and has the advantages of cost and system reliability. Compared with conventional passive LC filters, the number of magnetic components is the same, and only one additional winding is required. Previous studies only presented an ideal model without any related derivation, and the impact of any nonlinear components was not mentioned. In this letter, a further derivation of the nonlinear model is provided, and a comparison of the differences based on different characteristics of inductors is conducted to improve the circuit design.","PeriodicalId":100625,"journal":{"name":"IEEE Letters on Electromagnetic Compatibility Practice and Applications","volume":"6 4","pages":"149-154"},"PeriodicalIF":0.9,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10680882","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142844483","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It utilizes a polymer-based dielectric substrate and Y-Shield HSF 64 resistive ink with a conductivity of 640 S/m.

Results from ECM-backed DNN, ECM-assisted BeA, and full-wave simulation align closely with measured data, demonstrating a minimum reflection coefficient of −22.5 dB at the resonant frequency of 10 GHz with a bandwidth of 4.2 GHz (8.2–12.4 GHz) for normal incidence. This letter also examines the surface current distribution and electromagnetic (EM) properties, highlighting the absorber’s simplicity, flexibility, lightweight construction, polarization insensitivity, angular stability, and wideband characteristics, making it suitable for customized stealth and electromagnetic- compatibility (EMC) applications.","PeriodicalId":100625,"journal":{"name":"IEEE Letters on Electromagnetic Compatibility Practice and Applications","volume":"6 4","pages":"132-137"},"PeriodicalIF":0.9,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142844484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
