Abstract

Makalah ini menyajikan hasil studi pengukuran nilai Voltage Standing Wave Ratio (VSWR) dan power reflection factor (PRF) untuk berbagai jenis bahan dielektrik yang akan disisipkan pada saluran transmisi yang beroperasi di frekuensi 9 GH dan dibandingkan dengan saluran transmisi tanpa bahan dielektrik. Pengukuran dilakukan di laboratorium antena Politeknik Negeri Padang dengan menggunakan alat ukur penunjang komponen waveguide yang berfungsi menghasilkan nilai VSWR dan PRF sehingga didapatkan grafik gelombang berdiri dengan parameter tegangan dan jarak. Pengukuran dilakukan dengan menjadikan bahan dielektrik berbagai jenis dengan kondisi rangkaian terbuka. Pengukuran pertama dilakukan untuk bahan dielektrik jenis teflon berwarna putih diperoleh hasil VSWR sebesar 28,50 dengan PRF 86,90% sedangakan bahan dielektrik jenis plexiglass berwarna transparan nilai VSWR sebesar 12,39 PRF 72,35 % dan bahan dielektrik jenis PVC berwarna abu-abu VSWR 7,97 dengan PRF 60,39 %. Sedangkan untuk saluran transmisi tanpa bahan dielektrik ( tidak disisipi bahan dielektrik ) nilai VSWR 1,50 dengan PRF 4,01%.
