RF Energy Harvesting: Design of Printed Hexagon Antenna for ISM Band 2.4 GHz

In the recent wireless communication system, ambient RF sources allow the concept of RF Energy Harvesting system and join the green side by moving towards battery-less. In this paper, a printed hexagon antenna with a slot-loaded design of dimension 50x50x1.6 mm

optimized at 2.4 GHz (ISM Band, Wi-Fi) using Ansys HFSS EM 18.2. The reflection coefficient of the proposed antenna is -47.78 dB with a gain of 3 dBi. This paper gives the idea about a slot, spur and parasitic help to achieved better S
