20.500.12556/DiRROS-30230 Fractal resonator based frequency reconfigurable antenna with varying capacitive effect for wireless applications Frekvenčno nastavljiva antena s spreminjajočim se kapacitivnim učinkom za brezžične aplikacije, ki temelji na fraktalnem resonatorju A frequency reconfigurable antenna for wireless applications using a fractal antenna structure is proposed. The fractal antenna is composed of a step resonator type which has a mirror image at the vertical axis in the top with a slit and a parallel mirror image at the vertical axis in the bottom without a slit. The resonating frequency of the fractal antenna is controlled by a PositiveIntrinsic-Negative (PIN) diode. Two PIN diodes are connected between the top and bottom of the fractal antenna. With the varying capacitance effect, the four possible modes of operation of the diode are obtained at the dual resonating frequency of 2.7 and 3.2 GHz. The proposed design holds significant potential for applications in Fifth Generation New Radio (5G NR) n1 band, and Wireless Fidelity (Wi-Fi) access points due to its small size and easy control mechanism. The Specific Absorption Rate (SAR) values were analyzed and are within the safety limits. Predstavljena je frekvenčno nastavljiva antena za brezžične aplikacije, ki uporablja fraktalno strukturo antene. Fraktalna antena je sestavljena iz stopničastega resonatorja, ki ima zrcalno sliko na vrhu navpične osi z režo in vzporedno zrcalno sliko na dnu navpične osi brez reže. Resonančno frekvenco fraktalne antene nadzoruje dioda PIN (Positive-Intrinsic-Negative). Dve diodi PIN sta povezani med zgornjim in spodnjim delom fraktalne antene. S spreminjajočim se kapacitivnim učinkom se pri dvojni resonančni frekvenci 2,7 in 3,2 GHz dosežejo štirje možni načini delovanja diode. Predlagana zasnova ima zaradi svoje majhnosti in enostavnega mehanizma upravljanja velik potencial za uporabo v frekvenčnem pasu n1 nove radijske zveze pete generacije (5G NR) in dostopnih točkah brezžične povezave (Wi-Fi). Analizirane so bile vrednosti specifične absorpcijske hitrosti (SAR), ki so v mejah varnosti. reconfigurable antenna fractal PIN diodes wireless SAR konfigurabilna antena fraktali diode PIN brezžična povezava SAR true false true Angleški jezik Slovenski jezik Neznano 2026-06-17 19:10:21 2026-06-18 06:02:42 2026-07-02 03:59:34 0000-00-00 00:00:00 2025 0 0 Besedilo v angl.; str. 47-54 no. 1 Vol. 55 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-01-01 621.396.67 0352-9045 10.33180/InfMIDEM2025.104 281442051 MIDEM_55(2025)1p4.pdf MIDEM_55(2025)1p4.pdf 1 C3A51A3E1F37D49579EA3FD6954AC54D 734cc91b93dbe573292308690a5e460685faf07973a99c543b4ea073501e1a75 75844b11-7528-11f1-b0d9-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=46817 https://ojs.midem-drustvo.si/index.php/InfMIDEM/article/view/1957 1 6c8e846e-6a6f-11f1-97b2-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=45800 \"https://www.midem-drustvo.si/journal_papers/MIDEM_55(2025)1p4.pdf 1 6aef3f70-7528-11f1-b0d9-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=46794 https://ojs.midem-drustvo.si/index.php/InfMIDEM/article/view/1957 1 8e7d6f7d-6aca-11f1-a3b9-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=45844 RAZ_Manoharan_Abitha_Thangam_2025.pdf RAZ_Manoharan_Abitha_Thangam_2025.pdf 1 FA91C8D649C1CC43B7FC86CC0315F526 ea3fb13e59b3b6e2eb6951fcc310a3581439c4689ff3f62d78748061f334e21c 214bba02-7383-11f1-a785-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=46390 Strokovno društvo za mikroelektroniko, elektronske sestavne dele in materiale Informacije MIDEM 0 0 0
