Abstract

Indonesia Sea Radar untuk mengawasi lalu lintas laut sehingga dapat mencegah tindakan yang merugikan warga, dan juga tabrakan kapal apabila hendak merapat ke pelabuhan. Indonesia Sea Radar menggunakan Teknologi terbaru di bidang radar pengawas pantai yakni bernama Freguency Modulated Continuous Wave (FMCW), system tersebut menerapkan frekuensi gelombang radio berkelanjutan yang stabil dan diatur dengan sinyal modulasi triangular. Penelitian ini bertujuan untuk merancang, membangun dan membandingkan hasil fabrikasi filter mikrostrip interdigital frekuensi 9,4 GHz dengan metode open stub pada resonator dan defected ground structure pada ground plane untuk Teknologi terbaru di bidang radar pengawas pantai yakni Freguency Modulated Continuous Wave. Tujuan dari penerapan metode open stub dan defected ground structure untuk mengatasi pergeseran yang melebar dari hasil parameter seperti frekuensi, bandwidth, return loss, dan insertion loss pada saat simulasi ataupun fabrikasi filter mikrostrip. Hasil penelitian yang diperoleh yaitu Hasil simulasi menggunakan CST Microwave Studio 2019 frekuensi 9,4 GHz, bandwidth 68 MHz, insertion loss -0,488 dB dan return loss -12,923 dB sedangkan untuk hasil pengukuran yang dilaksanakan di Labolatorium Anechoic Chamber Pusat Teknologi Satelit menggunakan alat ukur Spectrum Analyzer Agilent Technologies adalah frekuensi 9.677 GHz, bandwidth 85 MHz, insertion loss -10,42 dB dan return loss -18.52 dB dengan Metode Penelitian Research and Development. Maka dapat dibuktikan dengan menggunakan bandpass filter interdigital dan penambahan metode open stub dan defected ground structure dapat mempersempit bandwidth dan meningkatkan nilai dari return loss dan insertion loss pada hasil simulasi. ***** Indonesia Sea Radar is to monitor sea traffic so that it can prevent actions that are detrimental to citizens, as well as ship collisions when they want to dock at port. Indonesia Sea Radar uses the latest technology in the field of coastal surveillance radar, namely Frequency Modulated Continuous Wave (FMCW), this system applies a continuous radio wave frequency that is stable and regulated with a triangular modulation signal.. This research aims to design, build and compare the fabrication results of a 9.4 GHz frequency interdigital microstrip filter using the open stub resonator method and defected ground structure ground plane for the latest technology in the field of coastal surveillance radar, namely Frequency Modulated Continuous Wave. The aim of applying the open stub and defected ground structure methods is to overcome wide shifts in the results of parameters such as frequency, bandwidth, return loss and insertion loss during simulation or fabrication of microstrip filters.. The research results obtained are simulation results using CST Microwave Studio 2019, frequency 9.4 GHz, bandwidth 68 MHz, insertion loss -0.488 dB and return loss -12.923 dB, while the results of measurements carried out in the Anechoic Chamber Laboratory of the Satellite Technology Center use a Spectrum measuring instrument. Agilent Technologies' analyzer has a frequency of 9.677 GHz, bandwidth 85 MHz, insertion loss -10.42 dB and return loss -18.52 dB with Research and Development Research Methods. So it can be proven that using an interdigital bandpass filter and adding the open stub and defected ground structure methods can narrow the bandwidth and increase the value of return loss and insertion loss in the simulation results.
