Abstract

Pada paper ini dirancang antena mikrostrip circular yang bekerja pada frekuensi resonansi 26 GHz dan 38 GHz.  Frekuensi ganda dibangkitkan dengan menambahkan U-slot pada bidang patch, kemudian penyesuaian ketinggian bertingkat pada slot untuk mendapatkan frekuensi tengah yang diinginkan. Hasil simulasi dari rancangan mikrostrip circular untuk frekuensi 26 GHz diperoleh nilai return loss -21,75 dB, VSWR 1,17 dan bandwidth 236 MHz, sedangkan pada frekuensi 38 Ghz  return loss -25,49 dB, VSWR 1,11 dan bandwidth 719 MHz.  Nilai gain sebesar 8,12 dBi dengan pola radiasi unidirectional.  Hasil rancangan telah memenuhi standar antenna untuk jaringan 5G, dengan radius (a) = 3,14 mm dapat diaplikasikan pada perangkat komunikasi nirkabel yang membutuhkan miniaturiasi antenna. Kata-kata Kunci : antena mikrostrip, circular, 5G

Abstract

Background: This article presents the implementation of a lightning protection system at the Cibanon Village Hall in Bogor as part of a technology-based community service program. Contribution: The initiative to install a conventional lightning rod in the Cibanon Village Hall building to protect electronic equipment. Method: The methodology includes site assessment, risk analysis, system design, and installation following international standards. Results: The results obtained from this study are the area that has the potential for lightning strikes, so it is recommended to install a conventional lightning rod installation with 4 (four) lightning rods on top of the building and 1 (one) rod in the ground with a depth of 7.5 m with a grounding resistance value of 2.02 Ohm. Conclusion: Shows the level of security requirements for the Cibanon Village Hall building against lightning strikes. The initiative also fostered community awareness and participation, highlighting its replicability in other rural areas with similar environmental threats.
