Abstract

Alat ukur Koefisien Pantul memanfaatkan teknologi microstrip, merupakan suatu alat ukur rasio gelombang berdiri (standing wave ratio/SWR). Perhitungan ukuran jarak, lebar strip konduktor dan
semua parameter-parameter menggunakan prinsip dasar teknologi mikrostrip saluran parallel. Alat ukur ini mempunyai kemampuan untuk mengukur Koefisien Pantul pada sinyal RF dalam cakupan frekuensi antara 3,5 MHz sampai 950 MHz. Dari hasil pengujian diperoleh jarak antar konduktor 1,56 cm. Untuk memperoleh impedansi 50 ï— maka ditentukan lebar strip konduktor masing-masing 6,3 mm, sedangkan
untuk mendeteksi sinyal yang akan diukur digunakan dioda germanium. Dari hasil pengujian alat ukur ini mempunyai kemampuan akurasi pengukuran sampai 950 MHz.
