Design of Rectenna for Energy Harvesting From Ambient GSM and WLAN Frequency Bands

Ambient wireless energy harvesting is a process of collecting unused wireless energy, which is abundantly available around us. Most of today's wireless communication services use GSM 900, GSM 1800 and WLAN frequency bands. The energy in these three frequency bands are available at most of the places at all the times. For harvesting this energy, this paper targets the design of a multiband antenna that encompasses the above said three frequency bands completely. For this purpose, a planar microstrip tri-band dipole antenna is proposed and designed. The antenna output drives a voltage doubler circuit through an impedance matching network (IMN). The simulations of antenna are performed in ADS, EMDS and EM-Pro simulation softwares. The targeted rectenna is simulated in ADS, which has the capability to harvest one third of the available power.
