Abstract

This paper proposes the design and implementation of a dual-function aperture-coupled spiral resonator (SR) antenna integrated with a compact impedance matching network (IMN) to achieve enhanced radiation performance and miniaturization. The antenna uses a two-layer FR4 substrate, where the SR is printed on the top layer as the radiating element and excited through a slotted aperture on the ground plane. To maximize power transfer, the IMN, consisting of an inter-digital capacitor (IDC) and a meandered inductor (MI), is embedded into the feed line on the bottom substrate. A comparative study between the conventional SR antenna and the proposed dual-function SR with IMN was conducted. Electromagnetic simulations and experimental measurements demonstrate that the integrated IMN improves the reflection coefficient (S11) by 43.64%, increases radiation efficiency from ~72% to ~87%, and enhances gain from ~3.2 dBi to ~4.8 dBi, while maintaining a compact footprint. The aperture-coupled feeding also contributes to bandwidth enhancement and isolation between the feed and radiating element. This dual-function design effectively resolves the trade-off between miniaturization and radiation performance, demonstrating its applicability for IoT, 5G, and wearable wireless devices.

Abstract

Energi merupakan sumber   kemampuan untuk melakukan aktifitas. Dengan energi dapat melalukan berbagai kegiatan. Energi listrik merupakan sumber energi untuk mendukung aktifitas. Listrik untuk mengaktifkan lampu, kumputer, pendingin ruang. Energi listrik dapat dibangkitkan dengan solar panel. Dengan solar panel energi membutuhkan sinar matahari, sehingga tidak memperlukan biaya untuk bahan baku. Prodi yang belajar dari pengabdian kepada masyarakat di SMK Pancakarya adalah prodi Teknik Komputer dan Jaringan(TKJ). Pengabdian masyarakat ini dengan melatih untuk desain,  memasang, mengukur dan perawatan  solar panel. Tempat pelatihan di laboratorium komputer, sehingga langsung bisa diterapkan di jaringan komputer.  Solar panel yang dipasang adalah 100 WP. Dengan pengabdian kepada masyarakat mempunyai pengetahuan tentang pemasangan, perawatan, pengukuran solar panel.
