Rancang Bangun Band Pass Filter Frekuensi 1.27 GHz untuk Teknologi Synthetic Aperture Radar
Abstract
ABSTRAK
Synthetic Apertur Radar (SAR) adalah teknologi radar yang digunakan untuk pengambilan gambar suatu objek dalam bentuk 2 atau 3 dimensi (penginderaan jarak jauh). Sistem tersebut  bekerja pada rentang frekuensi 1.265 sampai dengan 1.275 GHZ dengan frekuensi tengahnya 1.27 GHz. Agar sistem SAR ini dapat bekerja dengan optimal, dibutuhkan suatu perangkat filter yang dapat meloloskan frekuensi yang diinginkan. Sebelumnya sudah ada penelitian yang membuat perangkat ini di band frekuensi yang sama namun menggunakan bahan duroid 5880 dan resonator berbentuk kotak. Bandpass filter Pada penelitian ini dirancang dengan menggunakan metode Hairpin line dan bahan epoxy FR4. Hasil pengukuran menunjukkan nilai Return Loss masih cukup besar yaitu -9.33 dB dan nilai Insertion Loss minimal sebesar -13.51 dB.

ABSTRACT
Synthetic Aperture Radar (SAR) is a radar technology that used for taking an object in the form of 2 or 3 dimensions (remote sensing). It works in the frequency range 1.265 to 1.275 GHZ with a middle frequency of 1.27 GHz. SAR system can work optimally if it support a filter device that can pass the desired frequency. Previously there has been research that makes this device in the same frequency band but using 5885 duroid material and square resonator. Bandpass filter In this study designed using Hairpin line method and FR4 epoxy material. The measurement results of Return Loss values are still quite large  arround -9.33 dB and Insertion Loss minimum at -13.51 dB.
Keywords: Syntethic Aperture Radar, Band Pass Filter, Hairpin line
