20.500.12556/DiRROS-30240 A beam-split and gain-enhanced patch antenna using metamaterial superstrate for wireless communications Krpična antena z razcepljenim snopom in povečanim dobitkom z uporabo metamaterialne podlage za brezžične komunikacije This paper proposes multiband antenna-based Metamaterial (MTM) for beam splitting and gains improvement. Here, the focus is on developing the smart antenna using a Metamaterial Superstrate technique for modern wireless applications. The proposed antenna consists of two patches, the first one has a square shape placed on a Taconic FR-30 substrate, followed by the second patch constructed as a meander ring with two stubs for increasing the generated frequency bands. At the end of the design process, the proposed patch seems U-shaped to ensure the antenna beam is splitting at the desired frequency bands. In addition, the capacitive coupling is used for exciting the second patch, whereas the first patch is excited by conduction with a 50 Ω discrete port. Furthermore, a metasurface layer is designed and mounted on the second patch as a superstrate to increase the antenna gain toward the boresight direction. The results show a maximum gain of 8 dBi at 4.2 GHz with maximum dimensions of 108 × 108 mm2. Moreover, this antenna operates at additional frequency bands (2.6 GHz, 4.2 GHz, and 5.6 GHz), with a minimum reflection coefficient of -16.8 dB, -12.3 dB, and -30.6 dB, respectively. The proposed antenna is designed and analyzed using the CST MWS simulator. Članek predlaga večpasovno anteno na osnovi metamateriala (MTM) za razdelitev snopa in izboljšanje dobička. Pri tem se osredotočamo na razvoj pametne antene s tehniko metamaterialnega superstrata za sodobne brezžične aplikacije. Predlagana antena je sestavljena iz dveh krpic, prva je kvadratne oblike in je nameščena na substrat Taconic FR-30, sledi ji druga krpica, zgrajena kot meandrski obroč z dvema krakoma za povečanje generiranih frekvenčnih pasov. Predlagana krpica je v obliki črke U, da se zagotovi, da se antenski žarek razdeli na želene frekvenčne pasove. Poleg tega se za vzbujanje druge krpice uporablja kapacitivi sklop, medtem ko se prva krpica vzbuja s prevodnostjo z diskretnim priključkom 50 Ω. Poleg tega je zasnovana in nameščena metapovršinska plast na drugo krpico kot superstrat za povečanje ojačitev antene. Rezultati kažejo največje ojačenje 8 dBi pri frekvenci 4,2 GHz z največjimi dimenzijami 108 × 108 mm2. Poleg tega antena deluje v dodatnih frekvenčnih pasovih (2,6 GHz, 4,2 GHz in 5,6 GHz) z najmanjšim koeficientom odboja -16,8 dB, -12,3 dB in -30,6 dB. Predlagana antena je zasnovana in analizirana s simulatorjem CST MWS. patch antenna metamaterial superstrate gain beam splitting krpična antena metamaterial superstrat ojačenje delitev žarka true false true Angleški jezik Slovenski jezik Neznano 2026-06-17 19:14:18 2026-06-18 05:50:47 2026-07-02 03:59:36 0000-00-00 00:00:00 2025 0 0 Besedilo v angl.; str. 173-181 no. 3 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/InfMIDEM2025.304 281501699 MIDEM_55(2025)3p4.pdf MIDEM_55(2025)3p4.pdf 1 A3EB061512933488703244EE7B08E41A 6a2e36ec8f046cd2d547401cacd3db65f0d567be096df6f63423176bca057203 6ecf93cf-7528-11f1-b0d9-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=46800 https://ojs.midem-drustvo.si/index.php/InfMIDEM/article/view/2073 1 fa71f8c1-6a6f-11f1-97b2-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=45810 \"https://www.midem-drustvo.si/journal_papers/MIDEM_55(2025)3p4.pdf 1 695f4123-7528-11f1-b0d9-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=46777 https://ojs.midem-drustvo.si/index.php/InfMIDEM/article/view/2073 1 e5379aaf-6ac8-11f1-a3b9-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=45825 RAZ_Bashar_Bashar_S._2025.pdf RAZ_Bashar_Bashar_S._2025.pdf 1 B0005E3CD405096E592A76E77ED3707B 0a642a3d38ab1c10a8f91d1dfde9b657f0a3e32fbda5c0e4af68dafeac76289c 057f6638-7385-11f1-a785-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=46402 Strokovno društvo za mikroelektroniko, elektronske sestavne dele in materiale Informacije MIDEM 0 0 0
