 In this study, the effects of antenna types and
output powers on charging times of RF energy harvesting circuit were measured
and analyzed in detail. A measurement system which consisting of a signal
generator, an RF energy harvesting circuit, antennas and other devices was
installed for receiving the measurement samples. According to the measurement
results, the shortest charging time was obtained as 0.58 s at a distance of 20
cm, when 6.1 dBi antenna was connected to the RF energy harvesting circuit and
the output power of the signal generator was set to 17 dBm. In addition to
that, the longest charging time was evaluated as 25.01 s at a distance of 60
cm, when 1 dBi antenna was connected to the RF energy harvesting circuit and
the output power of the signal generator was adjust to 14 dBm. As a result, it
was determined that increasing of antenna gains and output powers and
shortening of distances between signal generator and RF energy harvesting
circuit decreased the charging times of the RF energy harvesting circuit in
this study.
