Abstract

Penelitian ini merancang sistem sensor RFID harmonik yang mengintegrasikan antena mikrostrip dual-band dan dioda Schottky HSMS-2850 untuk aplikasi Structural Health Monitoring (SHM). Sistem ini ditujukan untuk memberikan solusi pemantauan struktural yang efisien dan hemat biaya, dengan keunggulan dalam fleksibilitas pemasangan dan pemantauan waktu nyata. Antena dirancang bekerja pada frekuensi 1 GHz dan 2 GHz, menggunakan substrat FR4 dan diuji melalui simulasi CST Studio 2024, fabrikasi, serta pengukuran menggunakan VNA dan spectrum analyzer. Hasil pengujian menunjukkan kemunculan sinyal harmonik pada frekuensi 2 GHz yang sensitif terhadap kondisi material. Pada sampel 1 dengan jarak 15 cm diperoleh amplitudo sebesar −69,64 dBm, sedangkan pada sampel 2 dan 3 dengan jarak 21 cm diperoleh masing-masing sebesar −62,38 dBm dan −68,85 dBm. Variasi amplitudo ini menunjukkan kemampuan sistem dalam mendeteksi perubahan struktural akibat korosi, sehingga membuktikan potensi penggunaan RFID harmonik sebagai metode SHM pasif yang efektif untuk deteksi kerusakan dini.
