The system was designed to be able to convert RF energy of 1800
Mhz into a DC voltage large enough to power a small device. It
consists of a receiving antenna which is designed to capture the target
frequency, a matching circuit that increases the power acquired from
the antenna, and voltage multiplier which also acts as a AC to DC
rectifier [1][7]. The rectifier is needed to convert the sinusoidal
waveform into steady direct current for use in a device. The voltage
multiplier is needed because the devices cannot function without high
enough potential difference. This is done at the expense of lowering
the current [6]. Figure 2 shows the system overview.
