Abstract

Sejumlah radar menggunakan I/Q demodulator pada sisi penerima untuk melakukan pengolahan sinyal pantul dari objek yang diterimanya. I/Q demodulator merupakan suatu komponen yang berfungsi untuk memproses sinyal RF ke sinyal I (In-phase) dan sinyal Q (Quadrature). Pada I/Q demodulator, sinyal masukkan akan dikalikan dengan dua sinyal dari LO (Local Oscillator) yang masing-masing berbeda fasa 90 yang kemudian digunakan sebagai mekanisme pendeteksi fasa. Branch-line coupler merupakan suatu rangkaian penggeser fasa yang dapat diimplementasikan dalam membangun I/Q demodulator. Akurasi pergeseran fasa yang dihasilkan branch-line coupler akan memberikan pengaruh terhadap hasil deteksi fasanya. Dalam perancangan dan realisasi branch-line coupler diperlukan suatu kajian untuk mengetahui ketepatan pergeseran fasa yang diperoleh. Pada penelitian ini dilakukan, suatu analisa kerja branch-line coupler hasil dari suatu perancangan dan realisasi yang telah dilakukan untuk suatu deteksi fasa pada radar C-band dengan basis I/Q demodulator. Hasil penelitian menunjukkan bahwa nilai pergeseran yang mendekati 90 menyebabkan nilai fasa sinyal keluaran sebanding dengan fasa sinyal datang. Kata Kunci: I/Q Demodulator, Branch-Line Coupler, Penggeser Fasa

Abstract

Monitoring of glucose levels in the blood often using invasive methods. Blood sampling requires the puncture of a needle on the skin which is used for periodic blood tests over a period of time as a monitor for glucose levels in the blood. This method causes pain, discomfort, and has a risk of irritation/infection. Measurements will be made on three concentrations of glucose, namely hypoglycemia, normal glucose, and hyperglycemia. This technique is based on the relationship of permittivity, and the conductivity of the skin associated with glucose levels in the blood. A narrowband microstrip antenna that works at a frequency of 1,27 GHz. From the measurement results on the tested antenna, it can work at a frequency of 1,27 GHz in off-body and on-body conditions. After simulating the antenna with three glucose concentrations, an analysis was obtained, namely the smaller the Return Loss and VSWR values, the greater the concentration of glucose in the blood. Keywords: antenna, microstrip, glucose, blood glucose level (BGL), narrowband
