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

Program pengabdian masyarakat ini dilaksanakan di Kampung Gambut Siantan Hilir (Kuat Sihir) pada kelompok masyarakat pelaku UMKM dan Pokdarwis. Kegiatan ini dimaksudkan untuk menjawab isu rendahnya pemanfaatan potensi agroeduwisata dan UMKM lokal yang disebabkan oleh keterbatasan promosi, kelemahan inovasi produk, dan minimnya sarana pendukung wisata. Kegiatan KKM-PKM ini bertujuan untuk meningkatkan daya tarik wisata edukatif berbasis lahan gambut, memperkuat identitas UMKM melalui rebranding, serta mendorong partisipasi masyarakat dalam pengelolaan potensi desa secara berkelanjutan. Pendekatan yang digunakan meliputi Community Development, Asset-Based Community Development, dan Service Learning. Hasil program menunjukkan revitalisasi greenhouse sebagai elemen wisata edukatif, digitalisasi promosi melalui media sosial dan Google Maps, pemasangan plang penunjuk arah, serta rebranding UMKM melalui inovasi produk, packaging, katalog digital, dan akun promosi daring. Temuan ini memperkuat daya tarik wisata, meningkatkan identitas dan nilai jual produk, serta memperluas jangkauan pasar. Kesimpulannya, integrasi agroeduwisata dengan penguatan UMKM berbasis digital berhasil meningkatkan kemandirian dan pendapatan masyarakat desa serta mendukung pembangunan berkelanjutan.
