[ABSTRAK
Penggunaan energi alternatif untuk saat ini merupakan hal yang sangatpenting, dikarenakan makin menipisnya ketersediaan energi di alam. Energi alternatifini berasal dari potensial-potensial alam yang lain, yang dapat diperbaharui, dapatdihasilkan dalam waktu yang singkat, atau juga berasal dari akibat adanyapenggunaan potensi alam yang lain sehingga menimbulkan potensi energi yang tidakkita sadari kehadirannya disekitar kita adalah gelombang frekuensi radio atau yangbiasa dikenal dengan gelombang RF.Pada Tesis ini dibuat rectifier antenna dengan menggunakan antenamikrostrip patch lingkaran yang dapat digunakan untuk memanen energi RF padafrekuensi resonan 2,445 GHz dan mengkonversikannya menjadi energi DC, yangdapat digunakan untuk menghasilkan energi alternatif dari sumber daya yang belumdimanfaatkan.Dari hasil simulasi, parameter antena hasil perancangan diperoleh VSWR danreturn loss paling bagus sebesar 1,1664 dan -22,292 dB pada frekuensi 2,445 GHz,bandwidth sebesar 85 MHz, gain 6,882 dB, dan pola radiasi directional. Kemudian,dengan diberikan nilai Pin = 20 dBm, RL = 2 KΩ, dan jarak 100 cm rectenna mampumenghasilkan nilai Vout = 3,3 Volt dengan nilai efisiensi maksimal sebesar 82%.Dari hasil pengukuran, parameter antena hasil perancangan diperoleh VSWRdan return loss paling bagus sebesar 1,12 dan -25,08 dB pada frekuensi resonan2,445 GHz, bandwidth sebesar 72 MHz, dan gain 7,4 dB, dan pola radiasidirectional. Kemudian, dengan diberikan nilai Pin = 20 dBm, RL = 2 KΩ, dan jarak100 cm rectenna mampu menghasilkan nilai Vout = 0,967 Volt dengan nilai efisiensimaksimal sebesar 24%
ABSTRACT
Alternative energy becomes a very important issue due to the decrease energyavailability in the nature. For example, one potential energy that we didn?t realize itspresence around us is the Radio Frequency waves or commontly known as RFwaves. There is an effort to harvest the RF energy using rectenna technology.In this tesis a rectifier antenna using circular microstrip patch antenna thatcan be used to harvest RF energy at frequency 2.445 GHz is designed to convert theRF into DC energy. This design can be used to produce alternative energy fromresources that have not been utilized.From the simulation results, the results of the antenna parameters VSWR andreturn loss is 1.1664 and -22.292 dB respectively at frequency 2.445 GHz, has abandwidth of 85 MHz, gain .,882 dB, and radiation pattern is directional.
