Abstract:
Radio Frequency (RF) energy harvesting is an energy conversion technique
employed for converting energy from the electromagnetic (EM) field into the
electrical domain. So, the excess RF energy can be harvested from the
ambient surroundings to provide an alternative source of energy. This project
concerns with the construction of multiband microstrip patch antenna for RF
energy harvesting. This project focuses on the design of compact microstrip
patch antenna using geometry optimization and slot cutting techniques.
Performance of the patch antennas is first simulated using Keysight
ADS/Momentum software, where the effects of parameter and slot variations
are investigated. Then, the optimized patch antenna prototypes are fabricated
and tested in an anechoic chamber as well as in their actual operating
environment. The proposed microstrip patch antenna tuned at 2.4 GHz, 3.2
GHz and 4.5 – 4.7 GHz with return loss of 26 dB, 17 dB and 13 dB respectively.
The microstrip patch antenna can support under the band of different wireless
application as Bluetooth, WLAN/WiFi and WiMAX. The simulated and
measured results were presented.
