Selected Radio Frequency Power Harvesting by Using Broadband Triangle Monopole Patch

An increasing number of mobile electronic devices applied to various fields requires the availability of a portable power supply. Energy harvesting technique emerged as an environmentally friendly alternative energy resource. A preliminary evaluation of the ambient RF energy was done by measurement of received power in an urban area. In this research, design and manufacture of radio frequency (RF) power harvesting by implementing broadband triangle monopole microstrip antenna for RF power harvesting applications in frequency bands 1.700 to 2.500 MHz. An experimental RF energy harvesting system to harvest energy from the surrounding or zones near to transmitter did on this paper. The simulation results show the band frequency 1.13 GHz to 2.66 GHz obtained return loss ≤10 dB and bandwidth of 80.73%. The measurement results on the frequency band 1.09 GHz to 2.54 GHz obtained return loss ≤10 dB and bandwidth of 79.88%. When testing for 60 minutes in urban systems, obtained the output voltage 600.5 mV. The experiment proved that broadband triangle monopole microstrip antenna can harvest the ambient RF energy efficiently.
