Tesis ini membentangkan penuaian tenaga percuma daripada frekuensi radio menggunakan litar aktif dan pasif. Litar aktif beroperati menggunakan radio tangan dimana menhantar isyarat frekuensi kepada litar penerus. Voltan keluaran yang terhasil daripada litar aktif bergantung pada jarak antara antena dan radio tangan. Rekabentuk litar aktif yang terbaik di dalam tesis ini adalah litar tunggal dengan kapasitan yang tinggi. Litar penerus menggunakan antena discone dikenalpasti adalah pilihan yang terbaik untuk menyiapkan sistem ini dengan memasukkan diod silikon. Saiz dan sudut antena yang betul menghasilkan nilai maksimum keluaran voltan sebanyak 8.07 V. ______________________________________________________________________________________ This thesis presents the harvest of free energy from radio frequency using active and passive circuit. The active circuit is operated using a hand radio where the signal will transmit the frequency to the rectifier circuit. The output voltage collected from the active circuit depend on the distance between the antenna and hand radio. In this work the best active circuit designed was the single circuit with high capacitance. The rectifier circuit using discone antenna was found to be the best selection for the complete system incorporated the silicone diode. The appropriate size and correct angular position of the antenna yield a maximum output voltage of 8.07V.
