Language: English Typology: 1.01 - Original Scientific Article Organization: MIDEM - Society for Microelectronics, Electronic Components and Materials Abstract: 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.

Title:	Frekvenčno nastavljiva antena s spreminjajočim se kapacitivnim učinkom za brezžične aplikacije, ki temelji na fraktalnem resonatorju
Abstract:	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.
