In today’s scenario where every opportunity is explored to increase the lifetime of the wireless sensor network, Energy Harvesting (EH) based systems proved to be the game changers for enhancing the life of a node. As the Radio Frequency (RF) energy is available in abundance in the environment, it can be easily exploited as a source to scavenge energy. RF uses Wireless Power Transmission (WPT) where both power and data are transmitted from a source transmitter to the receiver. Firstly, microstrip patch antenna, loop antenna and spiral antenna are presented and based on their comparison, a modified H shaped antenna is used in the rectenna design for energy harvesting based sensor network. The receiving antenna is designed to select radio frequency of 1.943 GHz from the free space signals. The modified H shaped antenna is incorporated with a circular slot to increase bandwidth size. The results make the proposed rectenna design suitable for energy harvesting application because of the high gain 6.32 dBi, increased bandwidth upto 388 MHz and -24 dB Voltage Standing Wave Ratio.
